The results of a numerical simulation indicate that scanning equalization radiography (SER) provides the opportunity to use film/screen combinations of significantly higher contrast than currently practical in conventional chest radiography. These calculations which attempt to maximize overall image contrast ...

We compared computed radiography (CR) with a film digitizer as an image input device for transmitting radiographs to intensive care unit (ICU) displays.Limiting spatial resolution and low-contrast detectability performance were determined for a 600-speed screen-film combination and CR films. The same...

radiography [ra″de-og´rah-fe] the making of film records (radiographs) of internal structures of the body by exposure of film specially sensitized to x-rays or gamma rays. adj., adj radiograph´ic. body section radiography tomography. double-contrast radiography mucosal relief radiography....
Evaluation of the film contrast is made by comparing the γ's of the film produced at two or more X-ray energy levels; say 20 kV and 200 kV. To accomplish this, exposures at 20 kV are usually made of 12.5 mm (0.5 in.) thick steps in the carbon/epoxy step-wedge using several film...
and overall contrast and density.The statistically significant determination that the image quality of computed radiographs is at least as good as screen-film images allows confident use of computed radiography and enables radiologists to take advantage of its many other practical capabilities related to...
