ABSTRACT:
An apparatus for determining the probability that the shadow of a tumor designated on a radiation image of an object is the shadow of a malignant tumor on the basis of an image signal representing the radiation image includes a spectrum calculating means, a characteristic value calculating means, and a judging means. The spectrum calculating means obtains the spectrum distribution of the image signal D(r,.theta.) whose coordinates are expressed in polar form with the origin taken as the approximate center of the shadow. From the spectrum distribution the characteristic value calculating means obtains a characteristic value, which the judging means uses to determine the probability that the shadow of a tumor is the shadow of a malignant tumor.
