IMAGE PROCESSING APPARATUS AND COMPUTER READABLE MEDIA CONTAINING IMAGE PROCESSING PROGRAM
First Claim
1. An image processing apparatus comprising:
- previous image storing means for storing a previous image containing an abnormal shadow obtained by photographing a subject;
current diagnosis image storing means for storing a current diagnosis image to be diagnosed obtained by photographing the subject at a time later than the photographing time of the previous image;
aligning means for aligning the positions of the subject contained in the previous image and the current diagnosis image;
alignment information storing means for storing alignment information obtained by the aligning means;
abnormal shadow positional information storing means for storing positional information of the abnormal shadow on the subject in the previous image;
corresponding position calculating means for calculating, based on the positional information of the abnormal shadow and the alignment information, a corresponding position on the subject in the current diagnosis image, the corresponding position corresponding to the position of the abnormal shadow on the subject in the previous image; and
current diagnosis image abnormal shadow detecting means for detecting an abnormal shadow in the current diagnosis image from the vicinity of the corresponding position in the current diagnosis image.

Abstract
An image processing apparatus having improved detection performance for detecting an abnormal shadow, such as a tumor, and reducing a burden on the user is disclosed. In the image processing apparatus, an aligning unit aligns a previous image and a current diagnosis image with each other, and a corresponding position calculating unit calculates a position on a subject in the current diagnosis image corresponding to the position of an abnormal shadow on the subject in the previous image based on positional information of the abnormal shadow on the subject in the previous image and alignment information. A current diagnosis image abnormal shadow detecting unit detects the abnormal shadow in the current diagnosis image from the vicinity of the corresponding position in the current diagnosis image.
