Digital Radiography of the Chest by Self-Scanning Linear Diode Arrays

Abstract

Diode array digital radiography DADR is a method of radiographic imaging that combines the advantages of computertechnology with self-scanning linear diode arrays. These digital images are superior to those obtained by film in recording and displaying information in the lightestand the darkest areas of the film, resulting in a balanced image of the entire thorax without compromising detail, and at reduced radiation dose. This is a direct result of the widedynamic range, highcontrast sensitivity, fiber optic coupling, small diode size, short exposure time, and rejection of scattered x-rays of the system coupled with digital post-processing enhancement of the image displayed at 1024 x 1024 pixels.
