Analogous to window level. The brightness of an image determines how
light or dark the overall image appears.
Analogous to window width. The contrast defines the span of code values
and the relationship between the dark and light areas of the image.
Computed Radiography. Based on storage phosphor plates.
Digital Imaging and Communication in Medicine. A standard communication format that allows different types of equipment to work together when connected to a network.
Digital Luminescence Radiography
Detective Quantum Efficiency
Direct Radiography or Digital Radiography (based on a large area flat panel or CCD)
• direct-conversion flat panel detectors based on amorphous selenium
• indirect-conversion flat panel detectors based on amorphous silicon
• indirect-conversion based on charge-coupled device (CCD) detectors
Laser camera, where the use of a film
processing unit and of chemicals is not required. Laser light is exposed to film and after a thermographic process images are fixed on film.
Exposure range in which data can
be used to get acceptable image
A set of images, usually of the same body part, which are part of the procedure and have a common accession number.
Is used in cassettes to reduce scattered radiation and to increase sharpness.
Hospital Information System
Graphical display of the distribution of grey levels.
A network device that allows one or more devices to be interconnected to a network backbone.

An image which has been captured on a storage phosphor screen, but not digitized or processed. This is the image that the CR system extracts when it processes the cassette.
Look-Up Table. A set of values that can be mathematically applied to the digital image which alters the look of the image. The LUT is generated by the image processing algorithms of the

A DICOM Modality Worklist enhances your workflow by importing patient demographics and study information
from an information management system. Using the worklist eliminates errors from manual entry, lets exams
begin on time, and assures the information is catalogued correctly when sent to a PACS broker
