Texua builds the JC01-30W as a 3 MHz therapeutic ultrasound console for physiotherapy and soft tissue clinics. The beam is described as collimating, with a non-uniformity coefficient of 6 and an effective radiating figure of 4.5. Effective intensity reaches 1 watt per square centimetre, the duty cycle runs from 20 to 80 per cent in automatic and continuous modes, and the energy scale is 1 to 10. Applicator surface temperature is stated as not exceeding 45 degrees. The console carries an eight-inch screen, measures 370 by 85 by 320 mm, weighs 3.5 kg and takes 220 V at 50 Hz or 110 V at 60 Hz. Two power variants appear: 30 and 60 watts, with no other differences described.

Two of those figures deserve attention. Values between three and seven are generally accepted for a beam non-uniformity coefficient, and anything above eight is treated as unsafe, so 6 sits inside the band, in its upper half, which means peak intensity is around six times the average and the applicator has to keep moving.

The other figure is the one to query. Maximum penetration depth is given as 12 cm. At three megahertz, the half-value depth in tissue is commonly between one and two and a half centimetres, with roughly a quarter of the delivered energy remaining at four centimetres, which is why three megahertz is selected for superficial work and one megahertz for anything deeper. Twelve centimetres sit well outside that. The sheet does not say what the figure measures.

Medigear.uk lists the JC01-30W for UK business buyers. Before ordering, ask the seller what the depth figure measures and how, the effective radiating area (with units), the device class and declaration of conformity, and the calibration interval.

The JC01-30W is used in physiotherapy departments, sports and soft tissue clinics, podiatry, and rehabilitation services. At 3 MHz, it targets superficial structures, so it reaches tissues within roughly a centimetre or two of the skin: superficial tendon and muscle, myofascial trigger points, calcific deposits close to the surface, and scar or soft tissue work.

Deciding the indication list has to happen before delivery, not after. UK guidance advises against ultrasound for low back pain and sciatica, and against it for osteoarthritis, with therapeutic exercise as the core treatment in both. A 2025 rotator cuff tendinopathy guideline also recommends against it. Together, they cover a large share of a typical musculoskeletal caseload, so a service buying this console should be able to say what it will use it for and what it will not.

The duty cycle is where the clinical choice is made day to day. A continuous output drives the thermal effect and suits chronic presentations; pulsing at the lower end of the 20 to 80 per cent range reduces heating and is the usual selection in acute work. Having both on one console, with the ratio adjustable, is what lets a clinician follow a documented protocol rather than approximate it.

Buying runs through the usual routes. NHS musculoskeletal services, private physiotherapy and sports clinics, podiatry practices and teaching institutions each apply their own procurement rules, and a Class IIa or IIb device clears clinical governance alongside the rest. Conformity documentation is issued by the manufacturer and provided by the seller. Report adverse incidents involving the device to the MHRA through the Yellow Card scheme.

A beam non-uniformity figure is published.

Publishing the non-uniformity coefficient puts a number on how evenly energy leaves the head, which governs hot spots. Whatever the value, a manufacturer that states it has told a buyer something checkable.

The duty cycle range is stated with both modes.

Twenty to eighty per cent, across automatic and continuous switching, covers the acute and chronic ends of the usual protocol range. A clinician can select thermal or largely non-thermal delivery on the same console rather than treating whatever the machine happens to do.

An applicator temperature limit

Not exceeding 45 degrees at the head surface is a stated thermal boundary, which matters because the applicator is in contact with skin for the whole treatment. A published ceiling is something an operator can hold the machine to.

Intensity well inside the international limit

Effective intensity reaches one watt per square centimetre against a ceiling of three. That covers the range documented for superficial work at three megahertz, and it means the console can't run far beyond what those protocols call for.

Frequency and intensity that agree with each other

Three megahertz is the superficial frequency, and the intensity range published alongside it matches what the literature recommends for superficial treatment. The two specifications point to the same kind of work, which is not always the case on a sheet like this.

A console that takes almost no bench

Eighty-five millimetres deep, 3.5 kilograms, and an eight-inch screen. It sits at the back of a treatment room bench or on a small trolley, and one person moves it between rooms without thinking.

Dual rated voltage

Rated voltage covers 220 V at 50 Hz and 110 V at 60 Hz, which widens where a unit can be redeployed across a group, provided the variant supplied is confirmed at order.

The open questions are all answerable in writing.

The depth figure and its method, the radiating area with units, the class and certificate, registration, the calibration interval, and whether a one megahertz head exists. All sit in the manufacturer's file, and how completely they come back is itself information about the supplier.

Three megahertz operating frequency

The console operates at 3 MHz, which is the frequency selected for superficial structures. No one megahertz option is published.

Effective intensity to 1 W/cm²

Maximum effective intensity is published at one watt per square centimetre, against an international ceiling for therapy machines of three.

Energy scale 1 to 10

The output control is described as a one-to-ten scale. What each step corresponds to in watts per square centimetre is not stated.

Duty cycle 20 to 80 per cent

Pulsing is adjustable across that range, with switch modes described as automatic and continuous. Individual pulse ratios and the timer range are not published.

Beam non-uniformity coefficient 6

The ratio of peak to average intensity across the radiating area is published as 6. Accepted values run from three to seven, with anything above eight regarded as unsafe.

Collimating beam type

The beam is described as collimation type. No beam profile, divergence figure or measurement method accompanies the description.

Effective radiating figure 4.5

Published as "4.5 centimetres". Effective radiating area is properly an area in square centimetres, defined as the smallest area passing three-quarters of the acoustic power, so the units need confirming.

Applicator surface temperature not exceeding 45 °C

A stated ceiling for the temperature of the head in contact with skin. No measurement condition or duration is given.

Maximum penetration depth given as 12 cm

Published as a maximum penetration depth. Half-value depth at three megahertz is commonly put between one and two and a half centimetres, so what this figure measures needs establishing.

Eight-inch screen

Control is through an eight-inch screen. No resolution, preset protocol library, language options or session record function is described.

Two power variants

Machine power is published as 30 W and 60 W. No difference between the two is described beyond the power figure itself.

Console dimensions 370 × 85 × 320 mm

The unit is published at those dimensions, with a net mass of 3.5 kg; packed, it is 465 × 380 × 375 mm and 6.5 kg.

Dual rated voltage

Rated voltage is given as 220 V at 50 Hz or 110 V at 60 Hz. Whether a unit is switchable or built to one standard is not stated.

Applicators, calibration and marking not published

No applicator count or head sizes, no coupling gel provision, no calibration interval or method, no device class, no marking, no Approved Body number, no MHRA registration and no UK Responsible Person appears anywhere.

The JC01-30W publishes a good deal of output information: frequency, effective intensity, duty cycle range, beam non-uniformity, and an applicator temperature ceiling. Two entries need correcting or explaining before the page goes live anywhere: the radiating area units and the twelve centimetre depth figure, which sits well outside what three megahertz does in tissue. The larger question is not the machine but the indication list, because UK guidance advises against ultrasound for two of the commonest presentations a musculoskeletal service sees. Medigear.uk lists the JC01-30W for UK business buyers and can arrange delivery, installation, commissioning, familiarisation and service cover. Request the depth measurement method, the radiating area (with units), the device class and declaration of conformity, and the calibration interval from the seller in the quotation.

FAQ

Frequently Asked Questions

Everything buyers need to know about sourcing medical equipment through MediGear.

Not as a therapeutic depth; it should be queried rather than assumed. Absorption rises with frequency, so 3 MHz is absorbed quickly, and 1 MHz travels further. Published half-value depths for three megahertz sit between roughly one and two and a half centimetres, and standard dose tables put about a quarter of the surface energy remaining at four centimetres. That is precisely why three megahertz is chosen for superficial structures and one megahertz for deeper ones. A figure of twelve centimetres may be describing something else entirely, such as a depth at which pressure is still detectable rather than a depth at which a therapeutic dose arrives. Ask what was measured, by what method, and against what threshold.

It reads as a units error worth correcting before the figure goes into a catalogue. Effective radiating area is an area, expressed in square centimetres, and it is defined in the measurement standard for physiotherapy ultrasound as the smallest area through which three quarters of the acoustic power passes. A value of 4.5 square centimetres is an ordinary size for a treatment head. Four and a half centimetres as a length is not an effective radiating area at all. Ask for the figure with its units, and ask whether it was determined by the standard hydrophone scanning method.

Because it describes how evenly the energy leaves the head, and therefore how likely hot spots are. The ratio compares the highest intensity anywhere in the beam with the average across the radiating area. A low value means an even beam; a high value means concentrated peaks. Values from three to seven are generally considered acceptable, and anything above eight is unsafe. At 6, this sits inside the accepted band but in its upper half, which is a practical instruction as much as a number: keep the applicator moving, do not park it, and treat an area rather than a point.

It depends entirely on what you're treating. The international ceiling for therapy machines is three watts per square centimetre, so one is comfortably inside the safety limit. It also sets the working range. Protocols for superficial soft tissue at three megahertz commonly range from half a watt to one watt per square centimetre, which this covers. Protocols calling for one and a half to two and a half watts, generally for deeper or more chronic presentations at one megahertz, are outside it. The intensity ceiling and the frequency are coherent with each other, and both point at superficial work.

Not stated anywhere. Only three megahertz appears, which fixes the console to superficial structures. Services treating a mixed caseload usually want both frequencies available so that depth can be selected per presentation rather than per machine. Ask whether a one megahertz applicator exists for this console, whether it is interchangeable, and whether the unit recognises which head is fitted.

Two things that any buyer should read before ordering. For low back pain and sciatica, NICE guidance states plainly that ultrasound should not be offered. For osteoarthritis, the 2022 guidance likewise recommends against ultrasound, placing therapeutic exercise as the core treatment instead. A Cochrane review of chronic low back pain concluded that current evidence does not support therapeutic ultrasound in that condition, and a 2025 rotator cuff tendinopathy guideline also recommends against it. Evidence elsewhere is mixed, with weak positive signals for myofascial pain and calcific tendinitis and a small effect reported for knee osteoarthritis. None of that stops a device from being lawfully sold or used, but it does shape what a service should buy it for.

Superficial soft tissue presentations where the clinician judges it a reasonable adjunct, and where the indications guidance does not dominate the local caseload and advise against it. Myofascial trigger points, calcific tendinitis and superficial scar and soft tissue work are where the remaining evidence sits, and all are within reach of three megahertz. Any service introducing it should decide in advance which presentations it will and will not use it for, document that, and be able to explain the position. The specification is sound; the question is the indication list.

Not stated, and this is the recurring obligation the sheet leaves out. Output on a therapy ultrasound head drifts, and the measurement standard sets a tolerance between indicated and actual output. Surveys of machines in clinical use have repeatedly found large proportions outside that tolerance, with figures approaching seventy per cent reported by work associated with the UK national measurement laboratory, and devices delivering well above their displayed setting have been linked to skin burns. Verification needs a radiation force balance and is a service task rather than something done in the clinic. Ask for the manufacturer's calibration interval, the method, and who provides the service in the UK.

Under UK MDR 2002, an active therapeutic device intended to administer energy falls under Rule 9, giving Class IIa unless the energy may be administered in a potentially hazardous way, in which case it is Class IIb—either way, a UK A-Classed Body is involved, and a numbered certificate exists. The device must be registered with the MHRA before reaching the Great Britain market, and a manufacturer established outside the UK must appoint a UK Responsible Person. None of that is on the sheet. Ask for the class, the certificate and B-class number, the registration and the named responsible person.

Any service whose caseload is mainly low back pain or osteoarthritis, since guidance advises against ultrasound for both. Any clinic needing to treat at depth, because three megahertz alone will not reach it. Anyone unable to obtain the class, certificate and registration. And any buyer who cannot get a calibration interval, given how often machines of this type are found out of tolerance. For a clinic treating superficial soft tissue with a defined indication list and a calibration arrangement in place, the output specification here is unusually complete.
