Abstract
A tissue response in a predetermined unit of volume or area tissue of interest is determined by excluding some data of the adjacent tissues based upon a blood flow direction with respect to the tissue of interest. The exclusion is based upon a predetermined time-related parameter such as time-to-peak and mean-transit time in the fitted curves of the uptake of a contrast agent in the adjacent tissues and the tissue of interest. Furthermore, the blood flow direction is determined in terms of a 3D vector based upon a plurality of weighted individual vectors from the adjacent or neighboring voxels with respect to the voxel of interest.
