COMPUTER PROGRAM, AND IMAGE PROCESSING DEVICE AND METHOD

摘要

Provided is an analysis technique that ensures objectivity and quantitativeness in analyzing time-series images. The invention comprises: an image data storage unit (11) that stores image data of a plurality of time-series CT images obtained by capturing images of an organ of a subject to which a contrast medium has been administered; a target pixel extraction unit (31) that extracts an intra-organ pixel position which is the position of a pixel within a region of the organ; a change-over-time specifying unit (33) that specifies a change over time in the CT value of the pixel at the specified intra-organ pixel position on the basis of image data of a plurality of frames of the time-series CT images; and a functionalization processing unit (37) that specifies, on the basis of the specified change over time, an arrival time at which the contrast medium reached the organ at the intra-organ pixel position and a base value which is the CT value serving as a basis for the pixel at the intra-organ pixel position.
