Toshiba Tosbee SSA-240A
Toshiba · Model Tosbee SSA-240A
Ultrasound system. The SSA-240A (TOSBEE) has a unique ergonomic design that includes a Swing-Top mechanism, which allows the control panel and the monitor to be drawn toward the operator for convenient and comfortable use. It also has a simplified panel design that allows quick familiarity and easy operation. The variety of transducers of the TOSBEE - including convex, linear, mechanical sector and annular array transducers - give the system a wide variety of applications.
Key tips
- ·Never bypass a radiation interlock to "just get the image" - this is one of the few true zero-tolerance rules in BMET work.
- ·Trend image-quality phantom results over time - drift shows up before an outright failure does.
- ·Portable/mobile units take real physical abuse from transport - check wheel locks and cable strain reliefs more often than fixed units.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Transducer element failure
MediumSymptoms: Dropout, dead elements, image banding.
Root cause: Element delamination or cable damage from repeated use.
Transducer cable / connector wear
MediumSymptoms: Intermittent image loss, connector-wiggle artifact.
Root cause: Repeated flexing and connector strain.
Recon / system software hang
LowSymptoms: Frozen console, acquisition timeout.
Root cause: Workstation or storage degradation.
Display panel degradation
LowSymptoms: Dim image, color shift, dead pixels.
Root cause: Backlight or LCD panel aging.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily QC per modality: image-quality phantom test
- ·Tube and detector inspection
- ·Annual state-required radiation safety survey
- ·Vendor-scheduled preventive maintenance
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Transducer element failure
- Confirm the presentation - typically dropout, dead elements, image banding - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: element delamination or cable damage from repeated use.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the ultrasound transducer / probe per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
The firm initiated this recall of certain Toshiba Diagnostic Ultrasound Systems because it has been found that under certain conditions, the temperature of the transducer head may increase in 2D+PW mode or 2D+CDI (POWER, ADF) +PW mode. When the system is used under both conditions listed below, the temperature of the transducer head connected to the system may increase in temperature and possibly
- RECALL
Toshiba America Medical Systems Inc (TAMS) is initiating a field correction on the the Aplio XG model SSA-790A because it did not meet the requirement of clause 15b, IEC60601-1 which requires that the residual voltage shall not exceed 60V after 1 second from taking off the AC plug.
- RECALL
Panel Lock-up: When using dynamic image acquisition modes the panel may lock up, if the operator attempts to perform a still image capture. If the panel locks up the system will have to be rebooted to continue the examination which may cause a delay in completion of the patient examination.
- RECALL
Multiple problems including : (1) The surface temperature of the transducer tip can rise and exceed the limit set by the international standard. (2) Incorrect display of the TI indices on the display monitor. The displayed value is greater or smaller than the true TI value, and (3) Manuals contain incorrect values for MI/TI values.
- RECALL
When using the LV measurement function and making numerous measurements the value displayed on the image screen may on occasion not update correctly. The values that are stored in MDA (measurement display area) are correct and no issue has been reported with these values.
- RECALL
Transducer Surface Temperature : It was found during testing that when using the system in the 2DCDI + PW mode, with the Scale Graph function active, that the transducer surface temperature could exceed the 27 degrees Celsius limit as specified in the IEC safety standard.
- RECALL
If the measurement mode is started from the Doppler mode and then the sweep speed setting is changed by the assigned user function, the measurement of the time direction results don't correspond to the actual values.
