GXMO OHIO EXAM WITH COMPLETE QUESTIONS
AND CORRECT VERIFIED ANSWERS(DETAILED
ANSWERS) ALREADY GRADED A+ 100%
GUARANTEED TO PASS CONCEPTS!!!
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
Name some properties of XRAYS - ✔✔ANSW✔✔..1. highly penetrating, invisible rays;
2. electrically neutral;
3. polyenergetic/heterogenous energies;
4. liberate minute amounts of heat on
passing through matter;
5. travel ordinarily in straight lines;
6. travel at the speed of light;
7. ionizes gases indirectly by removing
electrons;
8. causes fluorescence in certain crystals;
9. cannot be focused by a lens;
10. affects photographic film;
11. produces chemical & biologic changes;
12. produces secondary & scatter
