GE HealthCare Precision MPi
GE HealthCare · Model Precision MPi
The compact size enables it to be installed in rooms as small as 12 feet (3.7 m) square. Flexible positioning opens access from both sides of the table, and the tilting/rotating table accommodates a full range of procedures. Cantilevered, 90/90 tilting table design and flexible C-arm positioning provides positioning flexibility and increases patient access for clinical versatility. Small footprint requires no ceiling support, reducing installation costs and conserving clinical space. 12-bit CCD-based camera, 1024 x 1024 imaging matrix and digital processing combine to create an imaging chain that produces images of extraordinary clarity.
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
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.
Fluoro dose-rate / image-brightness fault
HighSymptoms: Fluoro image too dark or bright, dose creep, ABC / ADRC not tracking.
Root cause: Image-intensifier or flat-panel degradation, or the dose-control loop.
No or inconsistent exposure / generator error
HighSymptoms: Exposure inhibited, generator error code, spot images under/over-exposed.
Root cause: HV generator / tank, tube, filament supply, or an interlock.
Table motion / tilt / spot-film device fault
MediumSymptoms: Table will not tilt or move, the spot-film / carriage will not position.
Root cause: Table drive, tilt motor, or the spot-film device drive.
Tube overload / cooling fault
MediumSymptoms: Exposures inhibited after a series, tube-heat alarm.
Root cause: Tube heat limit reached or a heat-exchanger / cooling fault.
Console / image-chain / PACS fault
MediumSymptoms: Console unresponsive, image freeze, images will not archive.
Root cause: Console PC, the image-processing chain, or the network.

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 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: Fluoro too dark/bright or dose creeping
- Image a phantom at a fixed field and distance and compare to baseline.
- Check the image-intensifier / detector performance via service diagnostics.
- Review the dose / ABC trend.
- Escalate an intensifier or detector degradation to the OEM.
- Re-verify dose rate against the room baseline after correction.
Symptom: Generator error / no exposure
- Record the exact generator error code.
- Confirm mains supply is within spec and all room interlocks are satisfied.
- Confirm the tube is not in a thermal lockout.
- Check the HT connections and exposure contactor.
- Escalate a confirmed HV-tank / tube fault; verify output after repair.

Documents & Manuals
Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
A reported incident of a monitor that fell from the suspension. A fall of a monitor could result in an injury to a patient or operator. Recall affects the single and dual LCD monitor suspensions used on Precision 500D Classical R & F system, Precision RXi 23A/32A Analog System, Precision RXi Digital system and Precision MPi fluoroscopic imaging systems.
- RECALL
The Precision MPi collimator did not contain a label identifying the device as being certified to comply with applicable requirements of the x-ray performance standard.
- RECALL
It was reported that when the GE Precision 500D foot pedal is repeatedly activated, a defect in the fluoro-timer will cause the dose measurement to report a higher value than was actually received by the patient. Patient will receive a lower dosage irradiation time which will result in indication of cumulative air kerma higher than that to which the patient was actually exposed.
- RECALL
Inaccurate cassette size display reading/ Inaccurate mAs reading: 1. When the device is in PBL mode and a larger film cassette is inserted into the table Bucky (replacing a smaller cassette) after a protocol is selected on the console, the collimator will not adjust to the larger cassette size. The collimator stays at the original smaller cassette size and allows the operator to take an exposure.
