ANALYZER AND METHOD OF INSPECTION BY SPLIT DOSE METHOD

摘要

PROBLEM TO BE SOLVED: To analyze the inspection result by using only images photographed during inspection by a split dose method. SOLUTION: An analyzer of inspection by the split dose method includes: a storing part 11 of rest images; a storing part 13 of load images based on radiation radiated from the same part of the same subject after giving RI; a radiation intensity ratio calculation part 15 for calculating a radiation intensity ratio of the rest images and the load images based on the rest images and the load images; and a change rate calculation part 17 classified by pixels for calculating the change rate of the load images to the rest images by removing influence due to a difference of the radiation intensity between a rest time and a load time based on the radiation intensity ratio.
