X-RAY CT APPARATUS, MEDICAL IMAGE PROCESSING APPARATUS, AND MEDICAL IMAGE PROCESSING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an X-ray CT apparatus capable of displaying a result of a blood flow perfusion analysis as information with time.

SOLUTION: A perfusion data acquisition means generates perfusion data of a subject from X-ray detection data detected by exposing the subject to X rays with a contrast medium injected into the subject. A perfusion parameter calculating means calculates perfusion parameters TTP being parameters with regard to time for each of a plurality of regions of interest based on a time variation TDC in density of the contrast medium for each of the plurality of regions of interest acquired from the perfusion data. A perfusion parameter display means divides time (TIME) being a calculation target for the time variation TDC in the density of the contrast medium into a plurality of time ranges (DIVIDED TIME RANGE) and sequentially displays images which include a plurality of regions of interest, mutually differ in time phases, respectively correspond to time ranges, and are masked so that only regions of interest having values of perfusion parameters TTP are displayed.
