Patent ID: 8498690

Claim:
A blood flow dynamic analysis apparatus for use in analyzing kinetics of blood flow in a subject after a contrast medium has been injected into the subject, the blood flow dynamic analysis apparatus comprising: a map generation device configured to compute a value of a parameter related to time change in a concentration of the contrast medium injected into the subject and to generate a map of the parameter; and a display condition determination device comprising: a reference value computation unit configured to compute a reference value of the parameter in the unaffected region in the map; and a standard deviation computation unit configured to compute a standard deviation of the parameter in the unaffected region in the map, wherein the display condition determination device is configured to determine a display condition for the map based on a threshold value of the parameter for discriminating between a lesion region where a lesion exists and an unaffected region where no lesion exists in the map, to determine the display condition for the map based on a difference between the reference value of the parameter in the unaffected region in the map and the threshold value of the parameter, to store beforehand the difference between the reference value of the parameter in the unaffected region in the map and the threshold value of the parameter, and to compute the display condition for the map based on the reference value of the parameter, the difference between the reference value of the parameter and the threshold value of the parameter stored beforehand, and the standard deviation of the parameter.
