Toshiba PET-511BTM
Toshiba · Model PET-511BTM
The PET-511BTM is a multiplane transesophageal transducer designed for use with Toshiba Diagnostic Ultrasound Systems for the visualization of the heart (and other organs) as a real-time ultrasound image.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Image dropout / dead element lines
HighSymptoms: Persistent dark bands or a missing sector that do not move with the anatomy.
Root cause: Failed piezoelectric elements in the array.
Intermittent image with cable flex
HighSymptoms: Image drops, flickers or is noisy when the cable or strain relief is moved.
Root cause: Broken conductors in the transducer cable or at the connector.
Acoustic lens / membrane damage
MediumSymptoms: Haze, comet artefacts, reduced penetration, a visible cut or bubble under the lens.
Root cause: Lens delamination or a puncture; drop damage.
Connector pin damage / not recognised
MediumSymptoms: System does not detect the probe or shows the wrong probe; bent or corroded pins.
Root cause: Damaged connector pins or a wet / dirty connector.
TEE / endocavity articulation or seal fault
HighSymptoms: (TEE / endocavity) fails a pre-use leak test, tip articulation loose or locked, bite-mark damage.
Root cause: Worn articulation cables / seals or a housing breach.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Dropout / dead lines
- Confirm the artefact stays fixed on screen and is not gel-bubble shadowing.
- Wipe off all gel, clean the lens and re-gel.
- Try the probe on a second compatible system, and a known-good probe on this system.
- Inspect the lens / face for cuts or delamination.
- If the probe is confirmed faulty, return it for repair - do not open the housing.
Symptom: Image drops when the cable is moved
- Flex the cable along its length and at both ends while imaging a phantom.
- Inspect the connector pins and the cable jacket.
- Confirm the connector is dry and fully latched.
- For TEE / endocavity, perform the electrical leak test.
- Return the probe for repair if the fault tracks the cable.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Potential degradation of detector performance.
- RECALL
It was found that if specific operations are performed in multi-phase helical scanning, the acquired raw data may not be saved due to a software problem.
- RECALL
Toshiba America Medical Systems Inc is removing the PET-511BTM Multi-plane Transesophageal Transducer from the market after receiving several reports of injury regarding the transducer. Bending or buckling of the flexible portion of the PET-511 BTM multi-plane transesophageal transducer (TEE) may result in injury including perforation.
