CR Computed Radiography, the process of creating digital radiographic images.
CT Computed Tomography, the process of creating digital tomographic images.
Cycle power Cycle power means to shut down and power up the Laser Imager.
DICOM Digital Imaging and Communications in Medicine. A TCP/IP-based protocol
for transmitting and receiving medical imaging and related data over a
network.
Dmax Dmax means maximum density. Dmax is the density of an area on the film that
has received maximum exposure.
Dmin Dmin means minimum density. Dmin is the density of an unexposed area on
the film.
DR Digital radiography, the process of creating digital radiographic images.
Film model The film model defines the print characteristics for a particular lot of film.
Key operator The person(s) designated by the department manager to receive applications
training and allowed access to password-protected areas to make system
changes.
Modality Medical equipment that actually generates medical images (for example, an
MRI).
Monotonic Continuously increasing. When a calibration sheet, which consists of strips of
increasing density (Dmin) to maximum density (Dmax), is read by the
densitometer, the density values must be monotonic (continuously
increasing). If they are not, an error message is generated.
MPDB Modality Preferences Database.
MR Magnetic Resonance.
N/A Not available or not applicable
PLUT Presentation Look-Up Table.
PMM Preventive Maintenance Module, a replaceable filter on the Imager.
QC step wedge Mammography Quality Control Test Pattern.
Service image An image used by service personnel for troubleshooting.
Shutdown The process of exiting current tasks and applications and turning the power
OFF.
SMPTE test pattern A Society of Motion Picture and Television Engineering monitor test pattern
that is used for analyzing image-quality problems.
Test type The type of test film that will be printed. Two film test types are available: a
density test film (SMPTE pattern) and a calibration film.
