How does the cassette with film image receptor work?
Special intensifying screen in the device emits light when struck by x-rays which imprints the image onto the film
Film must be fed into a processor in a darkroom before it can be read on a viewbox or illuminator
What is the PSP IP image receptor and how does it work in computed radiography (CR)?
Photostimulable storage phosphor imaging plate
Similar to conventional cassette with film, the PSP IP device contains an imaging plate; the imaging plate stores x-ray energy; the cassette must be fed through the CR reader which uses a laser to release the stored x-ray energy as light; the light is converted into a digital signal which is transmitted to a computer workstation that displays the image
Photostimulable storage phosphor image plate (PSP IP): A device, used for computed radiography (CR), similar in composition to a conventional intensifying screen that is housed in a specially designed cassette. The IP stores much of the x-ray energy it receives for later processing. After exposure, the cassette is inserted into a CR reader device, which scans the IP with a laser to release the stored x-ray energy pattern as light. The emitted light, constituting the radiographic image, is converted to digital format and is viewed on a computer monitor or may be printed on film
What is a a solid-state digital detector and how does it work?
A flat panel image receptor used in digital radiography
Directly converts the x-ray energy into a digital signal without a reader or processor
Can be built into the table or upright wall unit
Can also come in portable cassette form either tethered or wireless
