Osteometer Meditech DTX-200 DexaCare
Osteometer Meditech · Model DTX-200 DexaCare
The DTX-200 DexaCare assesses forearm bone density with optimised precision and accuracy. The DTX-200 DexaCare is a unique x-ray densitometer for the assessment of bone density in the distal part of the forearm. The forearm is an excellent site because the forearm is representative of the total body bone mass. The DTX-200 DexaCare has won world-wide recognition for enabling fast, easy, reliable, inexpensive and cost-effective assessment as well as follow-up of bone density. This has led to several thousand units being installed throughout the world. The DTX-200 DexaCare is a unique dual energy X-ray bone densitometer that gives you the opportunity to assess and follow up on the patients' bone density. With the DTX-200 DexaCare the physician has an easy and cost-effective method with a throughput of up to 50 examinations per working day. One of the unique features of the DTX-200 DexaCare is the automatic identification of the 8 mm distance between ulna and radius. This ensures that the same area is assessed every time. The excellent in vivo accuracy (>97%) and in vivo precision (>99%) makes DTX-200 DexaCare highly suitable for assessment of bone density and follow-up. The DTX-200 DexaCare is a truly automated system. Every calibration, positioning, assessment and calculation is performed automatically, minimising operator errors. The straight forward procedures together with minimal operator intervention make the DTX-200 DexaCare instantly operational. The extensive database allows comparison with age-matched peers (Z-score) and premenopausal peers (T-score). The DTX-200 DexaCare can be placed in the examination room without special installation and shielding requirements. The outstanding calibration system makes it possible to finish an examination within 4.5 minutes. Due to its integrated, dynamic approach, the DTX-200 DexaCare provides the facility to give the answer to the patient today.
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

Power supply fault
MediumSymptoms: Unexpected shutdown, unit won't power on.
Root cause: PSU or backup battery aging.
Recon / system software hang
LowSymptoms: Frozen console, acquisition timeout.
Root cause: Workstation or storage degradation.
Network / DICOM connectivity fault
MediumSymptoms: Images fail to transfer, PACS timeout.
Root cause: Network configuration or interface card fault.

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: X-ray tube overheating / filament failure
- Confirm the presentation - typically tube won't fire, heat-capacity alarm - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: filament wear, cooling failure.
- 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 x-ray tube insert 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.
Symptom: Detector calibration drift
- Confirm the presentation - typically image noise, artifacts, low SNR - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: flat-panel / sensor aging.
- 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 flat-panel detector 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.
