MEDICAL IMAGE DIAGNOSTIC DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce the error of decrease correction errors resulting from disagreement of positions of internal organs between a CT image and a medical diagnostic image while both of the images are photographed under appropriate conditions respectively.

SOLUTION: A CT image processing part 7a and a PET image processing part 7b detect the position of the liver on the basis of a CT image and a PET image respectively. The CT image processing part 7a calculates the displacement in the two positions of the lever. The CT image processing part 7a extracts the contour of the liver from the CT image, moves the internal area of the extracted contour in the CT image so as to decrease the displacement and modifies the CT image. The PET image processing part 7b performs the decrease correction on the basis of the modified CT image.
