Abstract
Digital video radiography (non-subtraction) has been investigated as a new technique for applications in general radiography. The imaging system consists of computer and array processor for 512 x 512 x 8 bit image acquisition and processing in combination with 14" and 9" image intensifiers and high signal-to-noise ratio TV cameras. A digital filter has been developed and implemented on the array processor which provides corrections for image intensifier-TV camera structure mottle and image shading. Preliminary clinical trials have been carried out for IVP and GI examinations. The wide dynamic range and high contrast sensitivity of the digital system allows windowing to view through dense areas in GI studies as well as the ability to visualize subtle contrast in IVP and GI examinations.
