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.
PET Detector Crystal Degradation
HighSymptoms: Reduced sensitivity, increased noise in emission images, quantitation drift
Root cause: Radiation damage and aging of lutetium oxysilicate crystals; PMT gain drift
CT X-Ray Tube Overheating
HighSymptoms: Thermal protection fault, reduced scan power, 'tube overtemp' error
Root cause: Inadequate coolant flow, thermistor failure, or RF circuit stress; Straton Z tube stress
Patient Table Motion Failure
MediumSymptoms: Table fails to move, stops mid-position, or error 'table position error'
Root cause: Stepper motor encoder failure, brake drag, or cable harness wear in Biograph PHS assembly
Vaporizer/Anesthetic Gas Leak (if applicable)
MediumSymptoms: Unstable gas flow, low fresh gas readings, safety interlock trips
Root cause: Vaporizer seal desiccation or loose fittings in the gas delivery system
Power Supply Unit (PSU) Fan Failure
MediumSymptoms: PSU overheating warning, intermittent system shutdowns
Root cause: Fan bearing wear, dust accumulation on heatsinks; critical for magnetron and electronics cooling

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: System displays 'PET sensitivity error' and images are noisy
- 1. Run system self-test diagnostic (syngo CT/PT) to confirm sensitivity values outside spec
- 2. Verify PMT high voltage settings via service interface; adjust if within allowable range
- 3. If values remain out of spec, replace PET Crystal Block Assembly - OEM alignment required
Symptom: CT scanner will not generate high voltage, tube error on standby
- 1. Check coolant flow rate and reservoir level; verify pump operation
- 2. Measure thermistor resistance at tube housing; compare to temperature curve
- 3. If coolant and thermistor OK, inspect RF circuit for arcing or component stress; replace CT X-Ray Tube if persistent
