APPARATUS AND PROGRAM FOR ASSISTING REPORT GENERATION

A burden in generating a follow-up observation report is reduced. The size of an abnormal shadow present on a current medical image obtained by imaging a subject is measured, and the size of an abnormal shadow present on a previous medical image, which has been obtained by imaging the same subject, at a position corresponding to the position the abnormal shadow on the current medical image is measured. A character string describing a change in the size is generated from the measured sizes of the two abnormal shadows, and a file of a report text, containing the character string, about a case shown in the previous and current medical images is outputted.
