RADIOGRAPHIC IMAGING AND EXPOSURE
CHAPTERS 1 THROUGH 10 COMPREHENSIVE
SOLVED QUESTIONS AND COMPLETE
ANSWERS
◉ exit/remnant radiationfl.
Answer: When the attenuated x-ray beam leaves the patient, the
remaining x-ray beam is referred to as _____?
◉ continuous beam of xrays to create images of moving internal
structures and viewed in real time.
Answer: fluoroscopy
◉ aka: scatter radiation.
Answer: fog
◉ masks the desired brightness on the image.
Answer: fog
◉ shape distortion - images that appear shorter than the true
objects.
Answer: Foreshortening
,◉ different shades of gray that can be stored and displayed by a
computer system.
Answer: Grayscale
◉ fewer shades of gray - greater differences between gray shades -
low mAs & high kVp.
Answer: high contrast image
◉ The device that receives the energy of the x-ray beam and forms
the image of the body part.
Answer: Image Receptor (IR)
◉ The exit or remnant radiation leaving the patient interacts with
the IR - is not visible.
Answer: Latent (invisible) image
◉ the ability to remove (eject) an electron.
Answer: Ionization
◉ photoelectric effect.
Answer: when ionization occurs within a diagnostic xray and
removes (ejects) an electron ____________________ happens.
, ◉ the pattern of stored energy on the exposed film; the invisible
image produced when the film is exposed to x-rays and that remains
invisible until the film is processed.
Answer: latent image
◉ great number gray shades - small variations between gray shades
- high mAs & low kVp.
Answer: low contrast image
◉ aka: size distortion - an increase in the image size of an object
compared with its true or actual size.
Answer: magnification
◉ it decreases.
Answer: what happens to magnification (size distortion) when SID
increases?
◉ when SID decreases.
Answer: when does magnification (size distortion) increase?
◉ the visible image once the IR is processed.
Answer: manifest image
