GXMO OHIO EXAM QUESTIONS AND
ANSWERS 100% CORRECT
collimator - ANSWER-a devise used to restrict xray beam
cassette - ANSWER-the rigid holder that contains the film and screens
Digital radiography acquires images that are
created or constructed from numerical data by
various types of image receptors such as
computed radiography (CR) and digital
radiography (DR). - ANSWER-acquires images that are
created or constructed from numerical data by
various types of image receptors such as
computed radiography (CR) and digital
radiography (DR).
The image receptor (IR) usually consists of the:
A. x-ray tube and the tube stand
B. cassette and the film
C. control console and the transformer
D. tube locks and the detent - ANSWER-B. cassette and the film
collimation and light beam restriction does what? - ANSWER-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 - ANSWER-radiolucent sponges, immobilization devices like sandbags,
retention bands, tape, PB devices, commercially designed equipment, mummification
The boxlike device attached under the tube housing that allows the limited operator to
vary the size of the radiation field is called a:
A. collimator
B. transformer
C. detent
D. tube port - ANSWER-A. collimator
Computed radiography (CR) is sometimes called a :
