Patent ID: 8755583

Claim:
A method for generating a functional data set of a perfused region of a human or animal body, comprising: injecting an contrast agent into a first artery supplying the region; recording first two images of the perfused region at different times before and after the injection of the contrast agent into the first artery supplying the region using an angiography device; supplying a first image data set comprising the first two images using the angiography device; selecting a second artery supplying the region that is adjacent to and different from the first artery supplying the region; separately injecting the contrast agent into the second artery supplying the region; recording second two images of the perfused region at different times before and after the separate injection of the contrast agent into the second artery supplying the region using the angiography device; supplying a second image data set comprising the second two images using the angiography device; generating a first functional data set by pixel-based calculation of a first perfusion parameter from the first image data set using a computation device that measures the perfusion of the first artery supplying the region; generating a second functional data set by pixel-based calculation of a second perfusion parameter from the second image data set using the computation device that measures the perfusion of the second artery supplying the region; and displaying the first and the second functional data sets on a screen.
