Abstract

PURPOSE:To exactly grasp a breakdown of the inside of internal organs, by fetching plural equal density area picture whose density levels are different, from one radioisotope image, and extracting its feature part as to each equal density area picture. CONSTITUTION:A radioisotope image of objective internal organs such as a liver is photographed by an image pickup device, an equal density line is extracted from its video signal, and plural equal density area pictures whose density levels are different are obtained. In this case, a picture by an output signal from an equal density line extracting device has width as to its border line and cannot be analyzed easily as it is, therefore, it is converted to a fine line by a fine line converting processor. Subsequently, plural equal density area pictures whose density levels are different are analyzed by a shape analysing device, a feature part is extracted as to each picture, and it is displayed on a display device.
