LUT Lookup table. A matrix which changes image values from one type of
measurement into another; for example, density to luminance.
Mandatory
destination
A network node to which all images from the CR 825/850 SYSTEMS
are sent.
mA Milliamperes. The measurement for the quantity of X-ray energy
emitted in a given time.
MIM Medical Image Manager.
mR 1/1000 of a Roentgen. Measure of exposure energy at the detection
device.
NVRAM Non-Volatile Random Access Memory. A read/write memory that
receives power from a BATTERY when necessary.
Offset Position of the GALVO when the laser beam first reaches the edge of
the SCREEN. In the fast scan direction, the offset is the “0” position.
Patient information The data about a patient.
PCMCIA Personal Computer Memory Card International Association.
PCMCIA CARD A memory card that includes the calibration data and the Collector
Profile.
PEC record The information describing the patient, exam, and the CASSETTE
used for the exam. The PEC record identifies a given image.
Photostimulable
luminescence
A condition in which PHOSPHOR discharges stored energy when
stimulated by infrared or visible light.
Pixel code value The value of each pixel of information that includes both the
measurement for samplings in the fast scan direction and the lines in
the slow scan direction.
Radiographic
Technologist
A person that provides diagnostic levels of radiation to make
diagnostic images.
Resolution Ability of an imaging system to detect separate lines that are close
together.
Retrace Motion of the laser beam across the SCREEN after it has scanned a
line.
