Kodak Directview CR 850
Kodak · Model Directview CR 850
Reads CR images, processes, performs image review, reprocesses (if necessary), and sends images to networked DICOM devices. Displays images on the attached flat-panel monitor; scans patient/cassette identification with the bar-code reader. Network up to ten remote operations panels to a single system. Use the ROP for remote patient and study data entry, bar code scanning, image review, reprocessing, and image routing functionality where it’s needed most. Built in Kodak PTS image processing software increases diagnostic confidence and reduces reading time. User name and password can be required to protect patient data. An automatic security screensaver guards against unauthorized viewing when system is unattended.
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.
Poor image quality / artefacts
HighSymptoms: Banding, streaks, ghost images, non-uniform density, dust artefacts.
Root cause: Dirty light guide / scanning optics, a worn erase-lamp array, imaging-plate wear, or contaminated transport rollers.
Plate / cassette transport jam or mis-feed
MediumSymptoms: Plate jams in the reader, transport error, plate not returned.
Root cause: Worn or contaminated transport rollers / belts, or a sensor fault.
Incomplete erase / residual latent image
MediumSymptoms: A faint previous image appears on the next exposure.
Root cause: Erase-lamp array degradation or a driver fault.
Laser / PMT scanning fault
MediumSymptoms: No or very noisy image, scan-error message.
Root cause: Scanning laser or the photomultiplier / detection chain.
Workstation / DICOM fault
LowSymptoms: Images will not display, annotate or send to PACS.
Root cause: Workstation PC or the DICOM configuration.

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: Poor image quality / artefacts (banding, streaks, ghosting, non-uniform density)
- Run the reader's cleaning and calibration / shading procedure.
- Clean the light guide, scanning optics and the transport rollers.
- Erase and re-image a plate to check for a residual latent image (worn erase lamps).
- Rotate in a fresh imaging plate / cassette to rule out plate wear.
- Escalate a scanning-laser / PMT / detector fault to the OEM.
Symptom: Plate / cassette jams or is not returned
- Clear the jammed plate per the manual and note where it hangs up.
- Inspect and clean or replace the transport rollers and belts.
- Check the transport / position sensors.
- Cycle several cassettes.
- Confirm reliable feed and return.
Symptom: Faint previous image on the next exposure (incomplete erase)
- Check the erase-lamp array for failed lamps / segments.
- Run an extended erase and re-image.
- Check the erase-lamp driver.
- Replace the erase-lamp array.
- Confirm a clean plate after a full erase.
Symptom: Images will not display, process or reach PACS
- Confirm the workstation is up and the DICOM store settings are correct.
- Send a test image and read the error.
- Check free disk space and the database.
- Restart the acquisition service.
- Escalate a workstation / network fault to IT.
