HIFU Cartridge Inventory Guide: Cost per Treatment, Shot Life and Reorder Planning

Stay In The Know

Expert advice. Very good deals. The absolute best (and worst) things we've tested lately.

A HIFU cartridge should be reordered before the clinic's inventory position reaches lead-time demand plus safety stock. Track each cartridge by exact part number, device model, depth, serial number, usable shots and status; calculate cost per treatment from landed cost and logged protocol use, not advertised shot life alone.

Quick answer: How should a clinic plan HIFU cartridge inventory?

Use four numbers for each depth: average daily shot use, usable shots remaining across active and reserve stock, total replenishment lead time, and safety-stock shots. Reorder when inventory position is at or below the reorder point. Order enough units to restore the target stock level, then validate the forecast monthly against actual treatment logs.

How to use this guide

The formulas are planning tools, not clinical protocols or industry benchmarks. All worked values are illustrative. Replace them with model-specific quotations, IFU or label information, clinic usage logs, observed replenishment times and approved protocols. Review the current LEFIS HIFU machine collection only to shortlist platforms; obtain cartridge compatibility, pricing, warranty and supply terms in writing for the exact configuration.

HIFU Cartridge Cost per Treatment Calculator

For readers who need the number immediately, the two formulas and worked example below deliver the primary calculation up front. Every figure used is illustrative — replace each input with the clinic's own supplier quotation, protocol logs, and operational data. The remainder of the article covers how to derive each input defensibly, how to plan inventory around it, and how to avoid the traps that skew the number.

Metric	Formula
Cost per usable shot	Landed cartridge cost ÷ Budgeted usable shots
Cost per completed treatment	Cost per usable shot × Shots used per treatment (sum across all depths)

Worked example — facial multi-depth protocol

Illustrative inputs only. For simplicity, this example assumes each depth uses a separate cartridge with the same $500 purchase price, $50 allocated freight and import cost, 10,000 rated shots and 8,500 budgeted usable shots. That produces $550 ÷ 8,500 = $0.0647 per usable shot for each depth. The sample protocol uses 150 shots at 1.5 mm, 400 at 3.0 mm and 300 at 4.5 mm. In a real comparison, calculate each cartridge separately because prices, rated life and usable life may differ by depth and model.

Cartridge Depth	Illustrative Shots Used	Cost per Usable Shot	Cartridge Cost per Treatment
1.5 mm	150	$0.0647	$9.71
3.0 mm	400	$0.0647	$25.88
4.5 mm	300	$0.0647	$19.41
Total	850	—	$55.00

At 85 percent utilization, cost is $0.0647 per shot. With the same $550 landed cost, 70 percent utilization produces $0.0786 per shot (about 21 percent higher than the 85 percent case), while 95 percent produces $0.0579 (about 11 percent lower). The range is asymmetric, so do not describe it as a simple plus-or-minus percentage. Use clinic logs to select and periodically revise the planning assumption.

Build a Cartridge Register and Verify Compatibility Before Calculating Cost

Cost calculations are unreliable when cartridges are recorded only as "HIFU head" or "4.5 mm cartridge." Every cartridge needs its own inventory record, and every cartridge needs verified compatibility against the specific machine it will run on.

What to record for every cartridge

Internal inventory ID, manufacturer, machine model and serial number, cartridge part number and serial number, focal depth, operating frequency, treatment mode, purchase date, activation date, purchase price, freight and import cost, rated shots, guaranteed minimum shots, remaining-shot count, warranty expiration, and storage location.

Cartridge-level vs model-level tracking

MODEL-LEVEL TRACKING	CARTRIDGE-LEVEL TRACKING
Records total cartridges owned	Identifies each individual cartridge
Cannot isolate a defect	Supports warranty evidence
Hides uneven use	Shows usage by depth
Weak reorder planning	Enables depth-specific forecasts
Difficult across locations	Supports transfers and accountability

Depth match vs system match

Two cartridges labeled 4.5 mm are not automatically interchangeable. Compatibility may depend on connector, handpiece, firmware, machine generation, shot-count chip, frequency, delivery mode, or serial-number lock. See HIFU frequency, intensity and pulse settings for depth and frequency conventions.

SAME DEPTH ONLY	CONFIRMED COMPATIBILITY
Both say 4.5 mm	Correct manufacturer part number
Similar external shape	Correct connector and firmware
May fit physically	Recognized by software
May be unsafe or unsupported	Covered by supplier warranty

OEM vs third-party cartridges

OEM cartridge: validated for the platform, supplier-backed protocol, clearer warranty path, predictable shot-counter behavior.

Third-party cartridge: may cost less, but compatibility may be unverified, may affect energy delivery, may void warranty, and may lack supplier support. Compatibility and warranty must be verified before use.

Understand What the Machine Counts as One Shot

Suppliers use "shot," "line," and "pulse" inconsistently. Two cartridges with the same shot rating may deliver different treatment capacity.

One trigger does not always equal one treatment line

A machine may count one trigger as one shot, one delivered line as one shot, one dot as one shot, one group of lines as one shot, or multiple thermal points as one cycle. Two cartridges advertised at "10,000 shots" may therefore support very different numbers of treatments.

Shot count vs line count

SHOT COUNT	LINE COUNT
Machine's usage unit	Number of treatment lines delivered
May represent one trigger	May include several lines per trigger
Useful for cartridge depletion	Useful for protocol and time planning
Must be defined by supplier	Must match delivery mode

Verify the counter with a live test

Record the starting count, deliver one single-line trigger, record the deduction, deliver one multi-line trigger, record the deduction, remove and reconnect the cartridge, restart the machine, then confirm the count remains accurate. Document the finding in the inventory policy so different managers use the same assumption.

Rated Shot Life vs Usable Shot Life

Rated shot life is the supplier's maximum advertised capacity. Usable shot life is the number of shots the clinic can reasonably use while maintaining acceptable output. The two are not the same. The size of the gap between them varies by device model, operator training level, protocol discipline, storage conditions, and the definition of “acceptable output” the clinic adopts — so this article treats the gap as a scenario input rather than an industry benchmark.

What reduces usable shot life

Factory tests, operator training, practice sessions, setup firing, aborted procedures, cartridge errors, accidental damage, early output drift, connector failure, warranty quarantine, expiration, and shots below the safety threshold.

Rated life vs guaranteed minimum

RATED LIFE	GUARANTEED MINIMUM
Headline maximum	Contractual floor
Assumes ideal use	Reflects defined conditions
Often used in marketing	Better for budgeting
May not address degradation	Should include failure remedy
Not always warrantied	Can support a claim

Use a conservative utilization factor

Estimated usable shots = Rated shots × planning utilization factor. Build at least three scenarios, but derive the percentages from clinic or supplier evidence. If no reliable history exists, the 70 percent, 85 percent and 95 percent cases used here are stress-test assumptions only, not labels for “poor,” “typical” or “mature” clinics. At 10,000 rated shots they yield 7,000, 8,500 and 9,500 budgeted usable shots. Replace a cartridge earlier when the IFU, device diagnostics, visible damage, repeated errors or authorized service guidance requires it.

Calculate HIFU Cartridge Cost per Shot and per Treatment

Basic cost-per-shot formula

Cartridge cost per usable shot = Landed cartridge cost ÷ Budgeted usable shots. Landed cost includes cartridge price, freight, customs or duty, import tax, payment fees, inspection expense, and any emergency-shipping allocation.

Worked example

Cartridge purchase price $500, shipping and import allocation $50, total landed cost $550, rated life 10,000 shots, budgeted usable life 8,500 shots. Cost per usable shot = $550 ÷ 8,500 = $0.0647. Round according to the clinic's accounting policy.

Advertised vs operating cost per shot

ADVERTISED CALCULATION	OPERATING CALCULATION
Purchase price ÷ rated shots	Landed cost ÷ usable shots
Ignores shipping	Includes delivery and import
Assumes every shot is billable	Includes training and waste
No risk allowance	Uses conservative capacity
Better-looking result	Better budgeting result

HIFU cartridge cost per treatment formula

HIFU cartridge cost per treatment = Cost per usable shot × Shots used during the treatment. When several cartridge depths are used, calculate each separately and add. LEFIS's HIFU machine cost and ROI for clinics guide separates cartridge depreciation, gel, staff time, maintenance, and training when discussing full-treatment economics.

MULTI-DEPTH TREATMENT COST STRUCTURE

DEPTH	SHOTS USED	COST PER SHOT	CARTRIDGE COST
1.5 mm	150	$0.0647	$9.71
3.0 mm	400	$0.0647	$25.88
4.5 mm	300	$0.0647	$19.41
Total	850	—	$55.00

Illustrative multi-depth facial protocol. Values match the worked example above ($550 landed cartridge cost, 8,500 budgeted usable shots at 85 percent utilization, $0.0647 per usable shot). Replace shots-used values with the clinic's own protocol data; where different depths use different cartridges with different landed costs, recalculate cost per usable shot per depth before summing.

Protocol estimate vs actual usage

PROTOCOL ESTIMATE	ACTUAL USAGE
Planned before treatment	Read from device after treatment
Useful for pricing	Useful for margin review
Assumes standard case	Reflects patient-specific plan
Used for booking model	Used for cost accounting

Add other variable expenses

The cartridge figure is not the full treatment cost. Also include coupling gel, disposable barriers, cleaning supplies, operator labor, room occupancy, payment-processing fees, and maintenance reserve.

Track Cost by Cartridge Depth

Blended averages hide inventory problems. A clinic may have low overall cartridge cost while running short of one high-use depth.

Face cartridges vs deeper body cartridges

FACE CARTRIDGES	BODY CARTRIDGES
Facial and neck protocols	Larger treatment zones
Often more frequent demand	May be less frequent
Protocol-dependent shots	Can be higher shot use
Higher reorder frequency	Depends on body bookings
Running out affects core menu	Overstock may tie up cash

Calculate a depth-specific monthly burn rate

Monthly shot burn by depth = Average shots per treatment at that depth × Monthly treatments using that depth. Do not divide stock equally across depths. Order volume should reflect real treatment mix, protocol usage, remaining shots, supplier lead time, seasonal demand, and cartridge shelf life.

Use Protocol Data to Forecast Cartridge Demand

Approved protocol templates convert clinical bookings into cartridge demand.

Build standard protocol templates

Each approved protocol should estimate treatment area, cartridge depths, expected shot range, and frequency of use. See HIFU facial protocols and downtime for facial-protocol context — the clinic should still use training applicable to its exact machine.

Compare forecast with actual use monthly

Usage variance = Actual shots used − Forecast shots. Investigate variance caused by incomplete training, different counting methods, changed protocols, or data-entry errors.

Set Reorder Points, Safety Stock, and Stock Levels

Ordering at zero remaining shots is not inventory planning. Reorder points, safety stock, and stock-level thresholds turn supplier lead time into a scheduling tool.

Separate the Reorder Trigger From the Order Quantity

Reorder point (shots) = Average daily shot use × Total replenishment lead time in days + Safety-stock shots.

Inventory position (shots) = Usable shots remaining in active cartridges + usable shots in reserve stock + confirmed inbound usable shots.

Reorder when inventory position is at or below the reorder point.

For a periodic review system, target stock (shots) = Average daily shot use × (Lead time + Review interval) + Safety stock. Units to order = MAX[0, ROUNDUP((Target stock − Inventory position) ÷ Usable shots per new cartridge)]. This separates the trigger from the quantity. If supplier pack sizes, minimum order quantities, expiry dates or different cartridge capacities apply, adjust the result before ordering.

Supplier dispatch vs total replenishment lead time

SUPPLIER DISPATCH TIME	TOTAL REPLENISHMENT TIME
Time before shipment	Time until clinic can use cartridge
Excludes transit	Includes transit
Excludes customs	Includes customs
Excludes inspection	Includes receiving checks
Often quoted by sales	Relevant to operations

Safety stock varies by operational risk

Higher safety stock is justified by international shipping, customs delays, no local distributor, single-machine dependency, high volume, multi-location operations, or uncertain supplier stock.

Low-volume vs high-volume clinic

LOW-VOLUME CLINIC	HIGH-VOLUME CLINIC
Slower cartridge depletion	Fast burn rate
Less cash tied in stock	Greater downtime cost
May hold one spare for core depth	May need several per depth
Higher overstock risk	Higher stockout risk

Minimum, target, and maximum stock levels

Minimum (reorder point): the inventory-position level that triggers replenishment. Target: the order-up-to level that covers lead time, the review interval and safety stock. Maximum: the highest authorized position after delivery, constrained by cash, shelf life, storage, model-obsolescence risk and supplier pack size. Do not use “minimum” to mean zero usable shots.

TABLE — INVENTORY FORECAST WORKSHEET

DEPTH	MONTHLY BURN	INVENTORY POSITION	LEAD-TIME DEMAND	SAFETY STOCK	REORDER TRIGGER
1.5 mm	600	2,500	300	200	When position ≤ 500
3.0 mm	1,200	4,200	600	400	When position ≤ 1,000
4.5 mm	900	3,800	450	300	When position ≤ 750
Body depth	200	1,500	100	100	When position ≤ 200

How to use the worksheet

Monthly burn (shots) = Average shots per treatment at that depth × Monthly treatments using that depth.
Lead-time demand (shots) = Average daily shot use × Replacement lead time in days for that depth.
Safety stock (shots) = Buffer volume covering supplier delay, customs risk, single-machine dependency, and booking pipeline. Increase for imported cartridges, weak local distribution, or full booking calendar.
Reorder point (shots) = Lead-time demand + Safety stock. Reorder when inventory position—not only the active cartridge counter—is at or below this level.
Target stock (shots) = Average daily use × (Lead time + Review interval) + Safety stock. Cartridges to order = MAX[0, ROUNDUP((Target stock − Inventory position) ÷ Usable shots per new cartridge)].

Copy this table into a spreadsheet, replace the illustrative values with the clinic's own data, and use inventory position versus reorder point as the alert. Add columns for review interval, target stock, usable shots per new cartridge, reserve stock, confirmed inbound stock and calculated units to order. The values shown are examples, not benchmarks.

Track Treatment Margin After Every Cartridge Replacement

Treatment contribution margin = Revenue − Cartridge cost − Other variable costs. This is not net profit — it excludes fixed overhead, financing, and taxes.

Forecast margin vs actual margin

FORECAST MARGIN	ACTUAL MARGIN
Uses expected shots	Uses logged shots
Estimated cartridge cost	Actual landed cost
Useful for price setting	Useful for management
Assumes full utilization	Reflects waste and failures
Reviewed before launch	Reviewed monthly

Recalculate margin when any input changes

Rerun the calculation after any change to cartridge price, shipping, currency, shot life, protocol, labor cost, promotional pricing, supplier, or machine model. For prepaid packages, reserve cartridge capacity for future appointments rather than treating full payment as unrestricted cash.

Monitor Energy Consistency and Plan Warranty Claims

Shot count alone does not prove a cartridge remains suitable for use. Follow the exact model's IFU, built-in diagnostics, error codes and supplier-authorized test process. Operator sensation or treatment outcome should not be used as a stand-alone energy-output measurement. The HIFU supplier guide explains which test records and warranty evidence to request before purchase.

First-use baseline vs ongoing check

FIRST-USE BASELINE	ONGOING CHECK
Establishes normal operation	Detects drift
Recorded at activation	Repeated at set intervals
Supports future comparison	Supports replacement decision
Useful for warranty	Useful for quality control

Possible indicators of cartridge decline

Quarantine a cartridge after visible housing or connector damage, repeated device errors, a failed manufacturer-defined self-test, abnormal heat or noise specified in the IFU, or an instruction from authorized technical support. Do not diagnose output drift from subjective sensation alone. Acoustic or electrical output testing belongs to the manufacturer or a qualified technician using an authorized procedure.

Quarantine status

Any questionable cartridge should be removed from active stock, labeled "Do Not Use," recorded in the inventory system, photographed, linked to its error record, and retained for warranty instructions.

Warranty claim structure

Ask whether the warranty is time-based, shot-based, or whichever comes first. Prepare purchase invoice, cartridge serial number, machine serial number, activation date, remaining shots, error code, photographs, and usage log for every claim. See HIFU training, warranty and after-sales support for the type of post-purchase information LEFIS publishes. A "free replacement" may still cost significantly when the clinic pays international freight, customs, and return shipping.

Include Treatment Speed in Cartridge Economics

Two cartridges with the same nominal cost per line may produce different operational costs if one delivers treatment much more slowly.

Cartridge cost vs appointment cost

CARTRIDGE COST	APPOINTMENT COST
Based on shot consumption	Includes room and staff time
Direct consumable expense	Operational capacity expense
Easy to calculate	Often overlooked
Ignores delivery speed	Affected by delivery mode

Faster delivery can reduce other costs

Shorter room occupancy, lower labor time, more appointments per day, and reduced operator fatigue. Speed should not override protocol control, treatment accuracy, client comfort, device limits, or safety.

Manage Cartridge Storage and Handling

Storage errors reduce usable life before the shot counter reaches zero.

Follow manufacturer-specific instructions

Controls may address temperature, humidity, sunlight, vibration, connector protection, cable handling, water requirements, orientation, cleaning, and transport. Cartridge construction varies by model — do not apply universal storage instructions.

Active stock vs reserve stock

ACTIVE CARTRIDGE	RESERVE CARTRIDGE
Assigned to a machine	Stored unopened or inactive
Count checked frequently	Condition checked periodically
Used in current treatments	Held for replacement
Higher handling exposure	Expiration and compatibility risk

First-expiring, first-out; document drops

When shelf life or activation deadlines apply, record expiration, rotate older stock first, and inspect packaging before use. A cartridge that appears undamaged may still require inspection after a drop — staff should report incidents rather than silently return items to stock.

Assign Cartridge Responsibility to Staff

Unassigned cartridges lose shots without explanation, and warranty claims fail when nobody can reconstruct usage.

Operator responsibility

Operators should record cartridge used, beginning count, ending count, treatment area, protocol, errors, and any damage.

Operations-manager responsibility

The manager should review remaining shots, usage variance, reorder dates, warranty cases, supplier lead times, cost per treatment, and quarantined stock.

Shared without logging vs controlled shared use

SHARED WITHOUT LOGGING	CONTROLLED SHARED USE
No individual accountability	Every use is recorded
Shot loss unexplained	Variance can be investigated
Damage difficult to trace	Incident linked to operator and time
Weak warranty evidence	Stronger service history

Test Replacement Supply and Remote Support

Test supplier support before the clinic is out of stock.

Ask a real inventory question before ordering

Which 4.5 mm cartridge is compatible with our exact model? Is it in stock? What is the price? What is the dispatch time? Does it require a firmware update? What is the warranty? What happens if it fails with unused shots?

Sales availability vs operational availability

SALES AVAILABILITY	OPERATIONAL AVAILABILITY
"We sell that cartridge"	Exact unit is in stock
No dispatch date	Confirmed lead time
No model verification	Part number matched
Verbal price	Written quotation
No support details	Warranty and activation included

Multi-Location HIFU Cartridge Planning

Multi-site clinics face inventory tradeoffs single-location clinics do not.

Central stock vs location-level stock

CENTRAL INVENTORY	LOCATION INVENTORY
Lower overall safety stock	Faster access
Better purchasing control	Less transfer delay
Requires internal shipping	More cash tied across sites
Easier bulk ordering	Protects local appointments

Standardize models; record transfers

A mixed machine fleet may create incompatible cartridges, duplicate inventory, more staff training, higher safety stock, and more obsolete stock. Every transfer should record sending and receiving location, cartridge serial number, remaining shots, condition, and staff approval.

Build a Monthly HIFU Cartridge Dashboard

A monthly view converts individual cartridge data into a management decision.

DASHBOARD METRICS

METRIC	GREEN	AMBER	RED
Inventory position by depth	Above target	Between target and reorder	At/below reorder
Days of stock remaining	Lead + review + buffer	Lead + buffer only	Below lead time
Monthly usage variance	Within set tolerance	Explained exception	Unresolved variance
Cartridge failures	No open issue	Quarantined; covered	Booking risk
Open POs on time	Confirmed; buffer covers	Delayed; buffer covers	No date; buffer short

Track active and reserve cartridges, inventory position by depth, monthly usage, treatments completed, shots per treatment, cost per completed treatment, forecast variance, quarantined units, warranty claims, days of stock remaining and open purchase orders. Define Green, Amber and Red thresholds from the clinic's lead time, review interval, booking exposure and approved risk tolerance; the labels are controls, not industry benchmarks.

HIFU Cartridge Planning Worksheet

Use the LEFIS HIFU machine collection to shortlist platforms, then verify every cartridge field against the exact model page, quotation, IFU and warranty schedule. The companion HIFU supplier guide explains how to request the document pack. Product names alone do not establish cartridge depths, compatibility, included quantities, shot life or body-treatment capability.

Information to request for each model

Cartridge depths, cartridge part numbers, frequency by depth, shot-count definition, rated shot life, guaranteed usable life, replacement price, cartridge warranty, machine compatibility, firmware requirements, current stock, shipping time, and storage instructions.

Compare C3-L and C6 by evidence pack, not model label

Review the C3-L and C6 product pages, but build the inventory comparison from written, model-specific evidence. Request the same five fields for each platform: exact cartridge part numbers and depths; standard versus optional items; shot-count definition and usable-life terms; replacement price and lead time; and warranty or failure-credit terms. Do not infer clinic fit from “2-in-1,” “3-in-1” or “D” labels.

HIFU Cartridge Inventory Mistakes to Avoid

Calculating with advertised shot life only

Understates cost when training, waste, errors, and early replacement are ignored.

Treating all depths as one inventory item

Can leave the clinic with cartridges in stock but none for its most-booked protocol.

Ordering only after the counter reaches zero

Exposes the clinic to shipping and customs delays with no buffer for booked patients.

Using cartridge price without landed cost

Freight and import costs can materially change cost per shot.

Keeping damaged cartridges in active stock

Questionable units should be quarantined and assessed before another treatment.

Overstocking before a machine upgrade

Future systems may use different connectors, firmware, or cartridge families.

Final HIFU Cartridge Inventory Checklist

Before setting service prices or placing a cartridge order, confirm the clinic has:

identified the exact machine model and created a compatibility matrix
recorded every cartridge serial number in one controlled register
defined what one shot means on the specific model
recorded rated shot life and set a conservative usable-shot assumption
calculated landed cartridge cost and cost per usable shot
logged shots per treatment and calculated multi-depth treatment cost
tracked usage by depth and forecast monthly shot demand
recorded supplier lead time and calculated reorder points
set safety-stock levels and minimum/maximum stock thresholds
inspected storage conditions and trained operators on logging
established quarantine procedures for damaged or drifting cartridges
reviewed cartridge warranty and prepared claim evidence
tested supplier support with an inventory question
reviewed treatment margins monthly against forecast
prepared a multi-location transfer process where applicable

Request a Model-Specific Cartridge Quotation

Unit price alone cannot show operating cost. Compare landed price, the supplier's shot-count definition, rated and guaranteed life, cartridge compatibility, replacement lead time, warranty remedy, failure-credit terms and the clinic's own cost per completed treatment.

Compare the LEFIS HIFU machines, then use the contact page to request a written, model-specific cartridge quotation. Ask the supplier to identify each cartridge by part number and depth and to separate standard, optional and replacement items.

Information to include in the quotation request

Provide the following operating data so compatibility, pricing and replenishment terms can be returned for the correct model. Use the supplier's written response as an input to the clinic's own planning worksheet; do not treat a supplier estimate as a substitute for usage logs, approved protocols or local financial review.

Field	What to Send	Why It's Needed
Machine model	Exact model number and serial number (e.g. C3-L 4D 2-in-1 SN…)	Confirms cartridge compatibility and shot-count definition
Cartridge depths in scope	Each depth being priced (e.g. 1.5, 3.0, 4.5, 8.0 mm)	Different depths carry different cartridges with different landed costs
Current replacement price (if known)	Landed cost per cartridge if a prior purchase exists	Anchors the clinic's cost calculation to its actual cost base
Rated cartridge shot life	Manufacturer's rated shots per cartridge for each depth	Baseline for the utilization-factor scenarios
Monthly treatments (by depth)	Average treatments per month using each depth	Drives monthly burn rate and reorder frequency
Country / landed cost basis	Destination country plus freight and customs treatment (DDP, DAP, EXW)	Shipping and duty allocation are material to cost per shot
Replacement lead time observed	Days from PO to usable stock in clinic (not just supplier dispatch)	Reorder-point calculation depends on total replenishment time, not dispatch time
Booking pipeline	Weeks of booked treatments held on the clinic calendar	Sets the safety-stock buffer against stockout during shipping delay
Contact and quotation reference	Named clinic contact, email, and any current supplier quotation reference	Supports model-specific follow-up and a written quotation

Submit the request through the LEFIS contact page and ask for a written response that identifies cartridge part number, compatible machine model, included shot-count definition, price basis, stock status, total replenishment estimate, warranty period, exclusions and the remedy for failure with unused shots.

FAQs

What is the HIFU cartridge cost per treatment?

Divide the landed cartridge cost by budgeted usable shots, then multiply by the shots used in the treatment. When a protocol uses several depths, calculate each cartridge separately and add the results. Landed cost should include freight, customs, and any inspection or emergency-shipping allocation.

How long does a HIFU cartridge last?

A cartridge lasts until its usable shot capacity is reached or it is removed earlier because of damage, output inconsistency, expiration, errors, or warranty instructions. Calendar life depends on monthly treatment volume and shots used per protocol.

How many treatments can one HIFU cartridge provide?

Treatments per cartridge equal usable shots divided by average shots used per treatment. Do not use rated shots without accounting for training, setup, waste, or multi-depth protocol use. A cartridge budgeted at 8,500 usable shots supports about 85 treatments at 100 shots each — fewer for higher-shot protocols.

Which HIFU cartridge depth is best?

No depth is universally best. Different depths are intended for different tissue targets and treatment areas. Inventory should match the clinic's approved protocols and patient demand rather than stocking every available depth equally.

Why are some HIFU cartridges so cheap?

Price may reflect manufacturing source, transducer quality, shot capacity, warranty, distribution model, or absence of local service. Compare landed cost per usable shot rather than unit price. A cheaper cartridge that fails early or voids warranty can cost more per completed treatment.

What happens when a HIFU cartridge runs out of shots?

The device may prevent further firing or require a replacement depending on the system. Clinics should reorder well before zero remaining shots to protect booked appointments — the total replenishment window includes supplier processing, dispatch, transit, customs, and receiving inspection.

Can HIFU cartridges be refilled or reset?

Only follow the manufacturer's authorized procedure. Unauthorized resetting or modification may affect performance, traceability, warranty, and safety. A reset does not restore the transducer's physical service life.

Do unused HIFU cartridge shots expire?

This depends on the cartridge design and supplier terms. Ask about shelf life, activation date, time-based expiration, storage conditions, and whether unused shots remain valid after long periods. Confirm the answer in writing before ordering large quantities.
