Toshiba PVF-357MT Ultrasound Probe Repair

The Toshiba PVF-357MT is a common candidate for repair rather than replacement. This page lists its typical failure modes, self-checks you can run, and the details a repair lab needs from you.

Manufacturer	Toshiba
Model	PVF-357MT
Probe type	Convex array
Compatible systems	Toshiba Sonolayer (SSA-270A)

You will usually see the PVF-357MT running on Toshiba Sonolayer (SSA-270A). Mention the console model with the fault description – connector and revision differences matter.

Curved arrays like the PVF-357MT see heavy abdominal duty, and the curved lens face takes the brunt of it – delamination and membrane wear typically show up before element failures do.

Common failure modes for the PVF-357MT

Match what you are seeing against the table below. The right-hand column reflects how faults of this kind typically assess – the actual verdict always depends on the individual probe.

What you see	Likely cause	Typically repairable?
Strain relief pulling away from the cable or gone rigid	Flex fatigue where the cable meets the probe or connector	Usually repairable
Visible nicks, grooves or staining on the lens surface	Mechanical wear or disinfectant damage to the lens	Usually repairable
Whole regions of the image blank across the array width	Widespread element or acoustic stack failure	Usually not economical
Pin damage or corrosion visible in the connector	Connector damage from forced insertion or drops	Usually repairable
Image cuts out when the cable is flexed	One or more conductors broken inside the cable bundle	Case by case
Bubbles or lifting at the lens face	The lens separating from the acoustic stack underneath	Usually repairable
Cable jacket cracked, wrinkled or discolored	Surface jacket wear – the conductors inside are often still good	Usually repairable

Check these before you ship the probe

• Run the system’s built-in probe test or element check if your console provides one.
• Inspect the lens face under good light for cuts, bubbles, lifting edges or discoloration.
• Check the strain reliefs at both ends for splits, stiffness or separation from the cable.
• Compare penetration and uniformity against a known-good probe on the same preset.
• Flex the cable gently along its length while imaging – intermittent dropout points to broken conductors.

Repair, exchange or replace — which applies to your PVF-357MT

Repair suits the PVF-357MT when damage is mechanical or confined – lens membrane, strain relief, cable jacket, connector hardware. Once element dropout spreads across large sections of the array, repair cost climbs toward replacement value and stops making sense. If uptime is critical, ask about exchange options while your probe is assessed.

What we need to quote your PVF-357MT repair

• A clear photo of the complete manufacturer and model label on the probe
• A description of the fault: what you see on screen and when it started
• The ultrasound system (console) the probe is used with
• Screenshots or photos of the image problem, if the fault is visual
• Photos of any physical damage – lens, housing, cable or connector

Images shown are representative and are not photographs of an individual unit. Nothing on this page claims OEM authorization or guarantees universal fit. Whether a specific PVF-357MT can be repaired, and on what terms, is confirmed in writing once the probe has been assessed.
