GXMO REVIEW Questions with Complete
Solutions
The opening in tube housing to allow primary beam to exit is called tube port
The area of the beam that strikes patient usually visualized with x-ray field light is called
radiation field
The center of primary radiation field cross hair in light fields central ray
The glass envelope maintains vacuum inside x-rays tube
What is the protective housing lead lined-limits leakage radiation
What is the tube port opening in protective housing allowing emission of primary
radiation (where useful x-ray exit)
what type of radiation is emitted through the protective tube housing Remnant radiation
,What type of radiation is emitted through the Protective Tube Housing? Leakage
How does attenuation effect x-rays the x-ray beam decrease in intensity as it passes
through the patient due to absorption and scatter
attenuation meaning the process of reduction, such as the attenuation of an x-ray beam by
reducing its intensity, the weakening of the degree of virulence of a disease organism, or
culturing under unfavorable conditions.
differential absorption absorption some tissue x ray more than other tissue
Image receptor can receive the remnant beam and forms the latest (invisible) image
remnant beam will contains what a transmitted primary radiation (x-rays leaving the
patient)
The (IR) image receptor forms what a latent image at the image receptor and when
processed becomes visible manifest image
,How does scatter radiation effect x-rays causes fog (general grayness) on the image that
decrease image contrast/radiation dose to machine operator
contrast means difference in tone that makes details visible
cassette / film screen image receptor a light tight container for film
film / film screen image receptor contains an emulsion sensitive to radiation and light
processing / film screen image receptor in a darkroom convert- invisible latent image to
visible image
cassette/computed radiography (CR) image receptor contains reusable, x-rays sensitive
phosphor plate that captures latent image
processor/computed radiography (CR) image receptor reads plate with laser, , erases
image from plate
, workstation/computed radiography (CR) image receptor displays image and
communicates with the network (PACS)
computed radiography (CR) image receptor eliminates the need for film. processor
chemistry, darkroom, view boxes, large filing area etc...
Flat panel detector/direct (digital) radiography (DR) Image Receptor converts x=rays
energy to electronic signal
Imaging computer/direct (digital) radiography (DR) Image Receptor translates electronic
signal into digital images.
information sent directly to computer for processing
eliminates processing step, detector remains in the room
What term refers to the decrease in radiation intensity as the beam passes through tissue
attenuation
What effect does scatter radiation have on the radiographic image? fog
