CR & DR: Assessment of Display daily
Monitor using SMPT or TG18-QC Results of assessment must be within
Test 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
