17 Cards in this Set
- Front
- Back
|
Backing Layer
|
soft polymer that protects the back of the cassette
|
|
|
Barcode label
|
label attached either to the cassette or the imaging plate that indentifies the plate for the purpose of matching the examination to the plate.
|
|
|
Barium fluorohalide
|
photostimulable phosphor located in the imaging plate
|
|
|
Cassette
|
rigid plastic housing for the imaging plate
|
|
|
Color Layer
|
area within the conductive layer where electrons are trapped
|
|
|
Conductive layer
|
layer of material that will absorb and reduce static electricity
|
|
|
Imaging Plate
|
thin piece of plastic with several layers of material that capture and store image data
|
|
|
Laser
|
amplification of stimulated emission of radiation, a device that creates and amplifies a narrow intense beam of coherent light
|
|
|
Phosphor center
|
(See Color Layer) -
area within the conductive layer hwere electrons are trapped |
|
|
Phosphor Layer
|
layer of photostimulable phosphor that "traps" electrons during exposure: usually made of phosphors from the barium fluorohalide family (e.g. bariums fluorohaldide, chlorohalide ro bromohalide crystals)
|
|
|
Photomultiplier
|
electronic device that amplifies light energy
|
|
|
Photostimulable luminescence (PSL)
|
light produced by a phosphor when struck by light or xray photons
|
|
|
Protective Layer
|
very thin, tough, clear plastic covering in the imaging plate for protection of the phosphor layer
|
|
|
Raster
|
zigzag electron scanning pattern
|
|
|
Reflective Layer
|
layer in the imaging plate that sends light in a forward direction when released in the cassette reader; this may be black to reduce the spread of stimulating light and the escape of emitted light; some detail is lost in this process.
|
|
|
Speed
|
in conventional radiography, speed is determined by the size and layers of crystals in the film and screen; computed radiography system "speeds" are a reflection of the amount of photostimulable luminescence given off by the imaging plate while being scanned by the laser.
|
|
|
Support layer
|
semirigid material in the imaging plate that fives the imaging sheet some strength
|
