LRA 211 WEEK 3 CH 8 & 9 QUESTIONS
AND ANSWERS UPDATED 2025/2026
Which of the following describes the process of radiographic image
formation?
Answer: Differential absorption
X-rays can eject electrons from atoms. This is known as:
Answer: Ionization
The x-ray interaction with anatomic tissue that is responsible for scattering is:
Answer: Compton interaction
Which of the following will increase beam attenuation?
Answer: Thicker anatomic part
Factors that decrease x-ray absorption include:
Answer: Increased x-ray beam quality
The range of exposure intensities an image receptor can accurately detect
defines:
Answer: Dynamic range
Digital image quality is improved with:
Large matrix size
Increasing the pixel bit depth will:
increase contrast resolution
, What type of imaging system uses an intensifying screen to convert x-rays to
visible light?
film-screen
Film-screen imaging has a wider dynamic range than digital imaging.
False
Dynamic imaging of internal structures can be visualized with a/an:
-film-screen.
-flat panel detector.
-image intensifier.
-a and b
A and B
The process of differential absorption to form an image is the same for digital,
film-screen, and fluoroscopy
True
A quality radiograph must include:
-visibility of anatomic structures.
