<P>PROBLEM TO BE SOLVED: To reflect an attention point of an interpreter on a similar image search. <P>SOLUTION: A similar case search device includes: an image feature extraction part 160 for extracting a plurality of image feature values from an interpretation object image; a report analysis part 150 for extracting an object disease name from an object interpretation report; a weight determination part 170 for, by using inter-binary relevant information showing relevancy between each image feature value and an object disease name via an interpretation item for every combination of the image feature values, determining a weight which becomes a larger value as the relevancy between the image feature value and the object disease name becomes high for every image feature value extracted by the image feature extraction part 160; and a similar case search part 180 for comparing a plurality of image feature values extracted by the image feature extraction part 160 with a plurality of image feature values extracted from a medical image included in case data registered in a case database by weighting those image feature values by the weight for each image feature value determined by the weight determination part 170 to search the case data including a medical image which is similar to the interpretation object image from the case database. <P>COPYRIGHT: (C)2013,JPO&INPIT |
