Chapter 1 (image Receptor/technical Factors) Flashcards
What is a image receptor?
Receives energy from a beam to form a image of a body part
Four types of IR devices
Solid State Image Receptor
PSP-IP
Fluoroscopic IR
Cassette with Film
What are the most common IT dimmensions
8x10 in
10x12 in
14 x17in
What are the technical factors radiographers use for images:
mA
kVp
Exposure time
What is mA
Milliamperage
What is kVp
Kilo-vault peak
What does exposure time mean
Seconds
Why do they select specific factors
To produce quality images using a generators control panel and technique book
Why do they use prime technical factors
Because of variations of electricity being delivered to the xray tube
What type of system is used to set technical factors
Manuel and automatic exposure systems (AEC)
What is a SID
Source-to-image receptor distance
