the IP is capable of storing an image formed by: - ANSWER✔✔-incident xray photon

excitation of phosphors


PSP: the xray photon energies reflect the: - ANSWER✔✔-differential absorption of the

anatomy directly above it


cassette is backed by ___ or ____ to absorb: - ANSWER✔✔-cassette is backed by

aluminum or lead to absorb backscatter xray photons from bouncing back and

interfering w image


cassette: made of anti-static material to protect: - ANSWER✔✔-(can usually be "felt")

protects against static electricity build up, dust collection, and mechanical damage


cassette: why do u wanna remove static electricity? - ANSWER✔✔-would contribute to

signal but doesnt represent anatomy (aka artifact)

, IP layers: 2. phosphor/active layer - ANSWER✔✔-a layer of PHOSPHOSTIMULABLE

PHOSPHOR that traps electrons excited by xray photons during exposure


IP layers: 2. phosphor layer: phosphors are what family? - ANSWER✔✔-barium

fluorohalide


IP layers: 2. phosphor layer: why might it contain a dye? - ANSWER✔✔-a dye would

differentially absorb the laser light within the reader to prevent as much "light spread"

as possible- light spread is bad- increases MTF


IP layers: 3. reflective layer - ANSWER✔✔--sends light in forward direction when

released in the reader


-may be black to reduce the spread of stimulating light/escape of emitted light


IP layers: 4. conductive layer - ANSWER✔✔-a layer of material that absorbs and

reduces static electricity


IP layers: 5. colour layer - ANSWER✔✔--located b/w active layer and the support that

absorbs the stimulating light (laser light) but reflects emitted light (blue light)


IP layers: 6. support layer - ANSWER✔✔-a semi-rigid material that gives the IP some

strength


-allows handling w/o damage


IP layers: 7. backing layer - ANSWER✔✔-soft polymer that protects back of cassette
