If your Toshiba PST-50AT is producing degraded images, failing probe tests or showing physical damage, this page helps you judge what is likely wrong and whether a repair makes sense before you commit to a replacement.
| Manufacturer | Toshiba |
|---|---|
| Model | PST-50AT |
| Probe type | Phased Array |
| Compatible systems | Toshiba Aplio 50 (SSA-700A), Toshiba Aplio XG (SSA-790A), Toshiba Xario (SSA-660A) |
The PST-50AT typically pairs with Toshiba Aplio 50 (SSA-700A), Toshiba Aplio XG (SSA-790A), Toshiba Xario (SSA-660A); the same fault can present differently between console revisions, which is why the host system is asked for with the quote details.
Phased arrays like the PST-50AT pack tightly spaced elements into a small footprint – edge-element failures distort the sector image early, and cardiac duty cycles accelerate cable fatigue.
Common failure modes for the PST-50AT
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? |
|---|---|---|
| Cable jacket cracked, wrinkled or discolored | Surface jacket wear – the conductors inside are often still good | Usually repairable |
| Bubbles or lifting at the lens face | Lens delamination from the acoustic stack | Usually repairable |
| Depth performance clearly below what this probe used to deliver | Ageing elements or lens delamination reducing acoustic output | Case by case |
| Split seams or impact marks on the probe body | A drop or knock; housings are routinely replaced or resealed | Usually repairable |
| Pin damage or corrosion visible in the connector | Connector damage from forced insertion or drops | Usually repairable |
| Visible nicks, grooves or staining on the lens surface | Mechanical wear or disinfectant damage to the lens | Usually repairable |
| Connector lock broken or hardware missing | Mechanical damage to the connector shell | Usually repairable |
| Sector image narrows or loses the apex | Element failure concentrated at the array edge | Case by case |
Check these before you ship the probe
- Photograph the complete manufacturer label – the exact revision matters for parts compatibility.
- Check the strain reliefs at both ends for splits, stiffness or separation from the cable.
- Run the system’s built-in probe test or element check if your console provides one.
- Compare penetration and uniformity against a known-good probe on the same preset.
- Inspect the lens face under good light for cuts, bubbles, lifting edges or discoloration.
Repair, exchange or replace — which applies to your PST-50AT
For the PST-50AT, think in terms of damage depth: surface and cable-level faults are usually repairable at a fraction of replacement cost; acoustic stack failures are evaluated case by case; extensive element loss generally means replacement. Send the symptoms and photos first – that determines the path before anything ships.
What we need to quote your PST-50AT 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 PST-50AT can be repaired, and on what terms, is confirmed in writing once the probe has been assessed.
