OHIO GXMO TEST MANUAL QUESTIONS AND
ANSWERS SET A+
✔✔Emulsion - ✔✔Material with which x-rays or light photons from screens interact and
transfer information
✔✔Epilation - ✔✔loss of hair
✔✔Erythema - ✔✔sunburn-like reddening of the skin
✔✔Ethics - ✔✔rules that apply values and moral standards to activities within a
profession to define professional behavior
✔✔Exposure - ✔✔Measure of ionization produced in air by x-rays or gamma rays
✔✔Exposure Indicator Number (EIN) - ✔✔A manufacturer-specific number that
correlates to the amount of radiation that reaches the digital image receptor
✔✔Exposure Switch - ✔✔The buttons, either on the control console or a hand switch
connected to the control console, that initiate the exposure
✔✔Exposure Time - ✔✔The length of time that the x-rays are turned on; the duration of
the x-ray exposure
✔✔Feed Tray - ✔✔The start of the transport system, where the film to be processed is
inserted into the automatic processor in the darkroom
✔✔Filament - ✔✔Part of the cathode that emits electrons, resulting in a tube current
✔✔Film Badge - ✔✔Pack of photographic film used for approximate measurement of
radiation exposure to radiation workers; sensitive up to 10 mrem
, ✔✔Filtration - ✔✔Removal of low-energy x-ray from the useful beam with aluminum or
another metal. It results in increased beam quality and reduced patient dose.
✔✔Fixed Aperture Collimator - ✔✔A collimator that is set at fixed dimension and cannot
be adjusted; also known as diaphragm
✔✔Fixed kVp Chart - ✔✔A technique chart where the optimum kVp value is established
for each projection and the mAs if varied according to the patient/part thickness
✔✔Flat Panel Detector - ✔✔A detector built into the table and upright wall unit that
consists of either a scintillation screen or a photoconductor, which converts the x-ray
photons directly into electrical signals; used in digital radiography
✔✔Fluorescence - ✔✔Emission of visible light only during stimulation
✔✔Fluoroscopy - ✔✔Imaging modality that provides a continuous image of the motion
of internal structures while the x-ray tube us energized; real-time imaging
✔✔Focal Spot - ✔✔Region of the anode target in which electrons interact to produce x-
rays
✔✔Focal Spot Blur - ✔✔Blurred region on the radiograph over which the operator has
little control
✔✔Focal Spot Size - ✔✔The measured size of a focal spot of an x-ray tube, a function
of the actual size of the cathode and the angulation of the anode surface
✔✔Focal Track - ✔✔Area on the rotating anode that receives electrons
✔✔Focused Grid - ✔✔radiographic grid constructed so that the grid strips converge on
an imaginary line; aligned with the direction of the x-ray beam
✔✔Focusing Cup - ✔✔Metal shroud that surrounds the filament
✔✔Fog - ✔✔Unintended optical density on a radiograph that reduces contrast through
light or chemical contamination
✔✔Foreshortening - ✔✔Reduction in image size; related to the angle of inclination of
the object
✔✔Free Radicals - ✔✔Uncharged molecule that contains a single unpaired electron in
the valence shell
