SYSTEM AND METHOD FOR QUANTIFYING MOTION ARTIFACTS IN PERFUSION IMAGE SEQUENCES

A method of evaluating the quality of a the quality of a match between two digitized images includes providing a pair of digitized images I1(x,y,z) and I2(x,y,z), each image comprising a plurality of intensities corresponding to a domain of points (x,y,z) on an 3-dimensional grid, calculating a motion quantification measure from said pair of images, the motion quantification measure |IΔ−| defined bywherein the sum is restricted to those IΔ<0, ƒ is a function, β is a constant, N− is the number of domain points with negative subtraction image values, and whereinIΔ(x,y,z)=I2(x,y,z)−I1(x,y,z).The images depict the same object but are acquired at different times.
