In conventional radioisotope scintigraphy, the image obtained is interpreted by human visual systems as qualitative patterns. However, the process sometimes results in losing much diagnostic information. This report deals with the utilization of a small computer for delineating the digital images and making its further computer analysis. The original data either derived from an Anger camera or from a whole-body scanner are directly stored inio the 4K core memories of the computer in digital form. The field of view contains about 1K image cells over the areas of 30 x 30 cm/sup 2/ to 50 x 180 cm/sup 2/. For kinetic studies of digital images, 8 x 8 image cells are adopted over the field of view and 32 frames of images are successively stored at the intervals of choice. As instructed by a program set up in advance for data processing, the computer performs mathematical procedures on the stored data, displaying the processed images so that human eyes can easily extract the diagnostic information from them. Five methods of image processing are described: smoothing; subtraction; contrast enhancement; differential imaging; and dynamic histograms on a regional area of interest. The practical applications of these methods are demonstrated. (auth)
