CR & DR: Assessment of Display daily
Monitor using SMPT or TG18-QC Test Results of assessment must be within established
Patterns limits
resolution, geometry, contrast, uniformity,
brightness, gray scale
- SMPTE/TG18-QC test patterns used for test
viewed 30cm from front of display device
- Assessment must be made of general image
quality & presence of artifacts
, CR: IP Cleaning & Inspection MONTHLY
- Visually inspect cassette for signs of obvious
damage (which may impact function)
- Clean external surface weekly
- Inspect CR screen (look for dust)
- Erase cassette (daily)
Damage to phosphor (white screen)
- Use dry wipes to clean; water will degrade
phosphor layer
- causes problems with reading & erasure
- phosphor missing = no signal = useless
Cracks/scratches in CR plate
- Less image-creating crystals/phosphor = less
signal
- throws off density and what the image actually
looks like
Damage to outside of cassette
- bent → thickness discrepancy → artifact (extra
attenuation spots)
- bad function → screen stuck in reader
- cracks/holes → fluorescent light from room or
dirt enters screen
– small quantities of fluoro = adds signal intensity
– high quantities of fluoro = erases information
Impacts of dirty screen
- light blocked, impacting reading & erasing of
cassette
- may lead to artifacts, ghosting, loss of signal
