collimator - ✔✔ANSW✔✔..a devise used to restrict xray beam
cassette - ✔✔ANSW✔✔..the rigid holder that contains the film and screens
collimation and light beam restriction does what? - ✔✔ANSW✔✔..decreases irradiated
tissue volume =decreases scatter radiation production which results in increased image
contrast-and decreased receptor exposure-reduces pt exposure-reduces occupational
exposure----IMAGE quality improves with smaller collimated fields...as long as anatomic
area isnt compromised
name some patient positioning aids or devices to assist in patient positioning and or
immobilization - ✔✔ANSW✔✔..radiolucent sponges, immobilization devices like
sandbags, retention bands, tape, PB devices, commercially designed equipment,
mummification
The mediium that transforms the xray beam into a visible image; radiographic film or a
phosphorescent screen - ✔✔ANSW✔✔..Image Receptor (IR)
Penetrating, ionizing electromagnetic
radiation having a wavelength much
shorter than visible light - ✔✔ANSW✔✔..XRAY
