COMPREHENSIVE EXAM 2026 QUESTIONS
STUDY GUIDE Q&A UPDATED
⩥ acute radiation syndrome. Answer: Radiation sickness that occurs in
humans after whole-body doses of 1 Gy (100 rad) or more of ionizing
radiation delivered over a short time not seen in diagnostic imaging
⩥ ALARA. Answer: (radiation exposure)As Low As Reasonably
Achievable
⩥ Anatomic Position. Answer: The position in which the patient is
standing erect; with the face directed forward, arms extended by the
sides with the palms facing forward, and the toes pointing anteriorly
⩥ Anatomically Programmed Radiography (APR). Answer: Technique
by which graphics on the console guide the operator in selection of a
desired kVp and mAs
⩥ Angiography. Answer: The fluoroscopic imaging of blood vessels
⩥ Anode. Answer: Positively charged side of an x-ray tube that contains
the target
,⩥ Anterior-Posterior. Answer: from front to back
⩥ American Registry of Radiologic Technologists (ARRT). Answer: The
world's largest credentialing organization in medical imaging,
interventional procedures, and radiation therapy; certify and register
technologists through administration of education, ethics and
examination requirements.
⩥ Artifact. Answer: Unintended optical density on a radiograph or
another film-type image receptor
⩥ American Society of Radiologic Technologists (ASRT). Answer:
Professional organization that promotes research, continuing education
and guidelines for radiography instruction
⩥ Atom. Answer: Smallest particle of an element that cannot be divided
or broken by chemical means
⩥ Atomic Number (Z). Answer: number of protons in the nucleus
⩥ Attenuation. Answer: absorption of the x-ray beam in matter, usually
the human body
, ⩥ Automatic Exposure Control (AEC). Answer: feature/device that
determines radiation exposure during radiography in most x-ray imaging
systems
⩥ Back-up time. Answer: when the exposure timer is manually set by
the operator to a time greater than the anticipated exposure time
⩥ Bergonie-Tribondeau law. Answer: principle that states that the
radiosensitivity of cells is directly proportional to their reproductive
activity and inversely proportional to their degree of differentiation
⩥ Binding energy. Answer: the energy required to separate a single
particle or group of particles from a molecule, atom, or nucleus
⩥ Biological Damage. Answer: the damage produced from exposure to
radiation
⩥ Bremsstrahlung x-ray. Answer: x-ray that results from interaction of
the projectile electron with a target nucleus, also known as breaking
radiation
⩥ Bucky Tray. Answer: a device that contains a moving grid
⩥ Caliper. Answer: a tool used for body part measurement
