AB - Early clinical application of an off-line image processing and analysis system for digital display in conjunction with computed tomography is described. The system consists of three operational subsystems: ( a ) a flexible disk for digital storage of absorption values in each of eight or more tomographic planes; ( b ) a high-speed interactive video system which displays the tomographic plane in correct geometry with the absorption values, which serve as the pictorial elements; and ( c ) a paper hard copy of the absorption values in a simulated gray-tone image of the tomographic plane in which the numerical values are the pictorial elements. Both the video and paper displays provide explicit numerical values of x-ray attenuation for each location on the tomographic plane in an image which combines analog and digital qualities.
