Chapter 9 Vocab

Computed Radiography (CR) One of two types of digital imaging systems. It is cassette-based digital imaging because the image of the body part is obtained using storage phosphor plates.
Conventional Radiography Radiography that uses film and intensifying screens within a cassette to form the image of the body part.
Digital Imaging The process of acquiring images of the body using x-rays, displaying them digitally, and viewing and storing them on a computer and in computer files.
Digital Radiography (DR) One of the two types of digital imaging systems. It is cassetteless because these systems do not use a cassette with phosphor is bonded to a flat panel detector built into the x-ray table.
Direct Conversion Detectors that convert the x-ray energy directly to an electric signal through an amorphous selenium detector.
Indirect Conversion A two step process in which the x-ray energy is first converted into light and then converted into an electric signal.
Photostimulable Phosphor A phosphor used in computed radiography (CR) plates to absorb the x-ray energy and store it until it is processed by a special unit and laser light.
Picture Archival and Communication System (PACS) The image managing system used in radiology departments. It consists of an extensive networked group of computers, server, and archives.
Postprocessing Using this process, any image of the body part can be further adjusted with the computer software to visualize areas of interest better. Two common techniques include subtraction and contrast enhancement.
