Before writing off a damaged Hitachi Aloka UST-987, compare its symptoms against the failure modes below. Many lens, cable and connector faults on this probe class are economically repairable.
| Manufacturer | Hitachi Aloka |
|---|---|
| Model | UST-987 |
| Probe type | Convex array |
| Compatible systems | Aloka SSD-1700, Aloka SSD-2000, Aloka SSD-4000 |
You will usually see the UST-987 running on Aloka SSD-1700, Aloka SSD-2000, Aloka SSD-4000. Mention the console model with the fault description – connector and revision differences matter.
Curved arrays like the UST-987 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 UST-987
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? |
|---|---|---|
| Vertical shadowing or missing scan lines on screen | Failed transducer elements or a broken conductor in the cable | Case by case |
| Noticeably weaker penetration than the paired probe | Ageing elements or lens delamination reducing acoustic output | Case by case |
| Grainy, low-detail image even after presets are checked | Lens wear or early element degradation | Case by case |
| Strain relief pulling away from the cable or gone rigid | Flex fatigue where the cable meets the probe or connector | Usually repairable |
| Cable jacket cracked, wrinkled or discolored | Surface jacket wear – the conductors inside are often still good | Usually repairable |
| Cuts, gouges or discoloration on the lens membrane | Mechanical wear or disinfectant damage to the lens | Usually repairable |
| Air pockets or peeling visible on the acoustic lens | The lens separating from the acoustic stack underneath | Usually repairable |
Check these before you ship the probe
- Compare penetration and uniformity against a known-good probe on the same preset.
- Examine the connector for bent or corroded pins, cracks and a working locking mechanism.
- Run the system’s built-in probe test or element check if your console provides one.
- 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.
Repair, exchange or replace — which applies to your UST-987
For the UST-987, 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 UST-987 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 UST-987 can be repaired, and on what terms, is confirmed in writing once the probe has been assessed.
