PATIENT CARE IN RADIOGRAPHY 9TH
EDITION TEST BANK 2026 STUDY GUIDE
QUESTIONS WITH ANSWERS AND
RATIONALS
⩥ anode. Answer: the electrode at which oxidation occurs; also, the
electrically positive, target end of an x-ray tube
⩥ attenuation. Answer: the process of reduction, such as the reduction of
x-ray beam intensity when it penetrates matter
⩥ bucky. Answer: a moving grid that limits the amount of scatter
radiation reaching an image receptor, thereby increasing the image
contrast
⩥ cassette. Answer: a device used in radiography for holding a sheet of
x-ray film and a set of intensifying screens. A cassette also may have a
grid to absorb scatter radiation.
⩥ cathode. Answer: negative electrode; the negative side of the x-ray
tube, which consists of the focusing cup(s) and the filaments(s)
⩥ collimator. Answer: a device for limiting the size and shape of an x-
ray beam
, ⩥ detent. Answer: a mechanism that tends to stop a moving part in a
specific location. Detents are built into x-ray tube supports to facilitate
ube placement at standard locations
⩥ electromagnetic energy. Answer: pertaining to magnetism that is
induced by an electric current. Also, energy in the form of
electromagnetic waves, such as light, x-rays and radio waves.
⩥ electron stream. Answer: the flow of negatively charged particles
across an x-ray tube, formed when the high positive electrical potential
at the target attracts electrons of the space charge, which move rapidly
across the tube.
⩥ filament. Answer: the source of electrons found at the electrically
negative cathode end of the x-ray tube. It is made of the element
tungsten.
⩥ fluoresce. Answer: the emission by certain crystals of light of one
wavelength when exposed to energy of a different, usually shorter,
wavelength
⩥ fluoroscope. Answer: a device used to produce a radiographic image
on a fluorescent screen or cathode ray tube monitor for visual
examination of internal structures in motion in real time.
