GXMO OHIO EXAMINATION TEST
COMPLETE STUDY GUIDE WITH SOLVED Q
AND A 2026
◉ 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
