Computed Radiology Flashcards
(35 cards)
is a digital radiographic imaging modality that uses a photostimulable storage phosphor imaging plate (PSP or IP), typically inside a cassette.
Computed radiography (CR)
As computer technology has advanced, so too has the ability of __ to produce images comparable to, and many instances better than, film.
CR Computed Radiography
It was in ____ that commercialization if CR imaging systems for use in diagnostic radiology began, when Fuji introduced their FCR-101 unit.
1983
Today there are atleast four manufacturers actively engaged in CR research technology development and marketing.
They are FUJI, AGFA GAVAERT, KODAK AND KONICA.
First of the famous company
Fuji
What are the Big Four
FUJI
AGFA GAVAERT
KODAK AND KONICA.
is a rigid sheet with several layers that are designed to record and enhance transmission of the image from a beam of ionizing radiation
PHOTOSTIMULABLE IMAGING
The ____ consists of a durable, lightweight plastic material backed with a thin sheet
of aluminum that absorbs xray.
cassettes
is the chemical coating on a phosphor plate
in a computed radiography system.
PHOTOSTIMULABLE PHOSPHOR (PSP)
Instead of _____ (found in film imaging ) there is an anti -static material
that protects against static electricity build up, dust collection, and
mechanical damage to plate.
intensifying screen
This was followed by other manufacturers, most notably _____ whose systems became popular as well.
Kodak and Agfa
thin, tough, clear plastic that protects the active phosphor layer.
PROTECTIVE LAYER
a. Made of carbon fiber or Magnesium
PROTECTIVE LAYER
b. No image producing qualities
PROTECTIVE LAYER
This layer of Photostimulable phosphor from the barium
fluorohalide family.
PHOSPHOR OR ACTIVE LAYER
a. Ability to store and release energy.
PHOSPHOR OR ACTIVE LAYER
Layer of material that grounds the IP from electrostatic charge
CONDUCTIVE LAYER
a. Increases spatial resolution
by absorbing light.
CONDUCTIVE LAYER
Semi -rigid material that gives the imaging sheet some strength.
SUPPORTIVE LAYER
Sends light in a forward direction when
released in the reader.
LIGHT SHIELD ( REFLECTIVE LAYER)
Prevent unwanted light from affecting the unexposed latent image.
LIGHT SHIELD ( REFLECTIVE LAYER)
Soft Polymer that protects the back of the cassette.
BACKING LAYER
a. Prevent unwanted background radiation from affecting the unexposed latent image.
BACKING LAYER
The ___ is loaded into a cassette that looks much like a radiographic
and intensifying-screen cassette.
