Patent ID: 11813106

Abstract:
An object of the present invention is to provide an analysis method capable of analyzing time-series images by a method simpler than ever. A computer program that is an application example of the present invention is a computer program for an image processing device including a storage unit that stores therein image data including time-series computed tomography (CT) images in a plurality of frames, of an organ of a subject captured after a contrast medium has been administered causes the image processing device to execute: a first step of determining a change-over-time of a CT value on the basis of image data including CT images in the plurality of frames; a second step of determining a predetermined slope that is a slope of the CT value with respect to a predetermined time on the basis of a change-over-time of the CT value determined in the first step; and a third step of approximating a change-over-time of the CT value with a predetermined function on the basis of the predetermined slope determined in the second step.
