Automatic exposure control (AEC)
In an X-ray generator, mode of operation in which one or more loading factors are
controlled automatically in order to obtain at a preselected location a desired quantity
of radiation.
Automatic exposure rate control
In an X-ray generator, mode of operation in which the rate of emitted radiation is
controlled automatically by control of one or more loading factors in order to obtain at a
preselected location and in a preselected loading time a desired quantity of radiation.
Beam limiting device
Device to limit the radiation field.
Becquerel (Bq)
The special name for the SI unit of activity. One becquerel is one reciprocal second or
1 s-1. 3.7 × 10
10
Bq = 1 Ci.
Bootloader
General: a program that does the job of loading the OS kernel of a computer.
Barracuda bootloader: Miniature program stored in cabinet and modules which
normally just starts the Firmware. It is used more when the Firmware is updated. See
Firmware.
Centigray
0.01 gray. 1 cGy equals one rad.
Cinefluorography
The production of motion picture photographic records of the image formed on the
output phosphor of an image intensifier by the action of X-rays transmitted through the
patient (often called cineradiography).
Cineradiography
Indirect radiography of moving objects usually in rapid series on cine film.
Collimator
See beam limiting device.
Compensating filter
Filter used in order to modify the distribution of absorbed dose rate over the radiation
field.
Computed tomography (CT)
An imaging procedure that uses multiple X-ray transmission measurements and a
computer program to generate tomographic images of the patient.
Continuous mode
For an X-ray generator, mode of loading an X-ray tube continuously as in radiotherapy
or in radioscopy.
Conversion factor (of an image intensifier)
The quotient of the luminance of the output phosphor of the image intensifier divided
by the kerma rate at the input phosphor.
SI unit: cd/m² / Gy/s = cd·s/Gy·m²
