Method and apparatus for carrying out a comparison between a left and right brain of a patient

摘要

For the comparison between a left and right brain of a patient on the basis of medical 2 - d - or 3 - d - perfusion - image data sets, the brain (2) of the patient in brain regions (g1 - g6), wherein the number of the brain regions (g1 - g6) corresponds to a straight line number n, a number n / 2 of the brain regions (g1 - g6) in the right, a number n / 2 of the brain regions (g1 - g6) is arranged in the left cerebral hemisphere and each arranged in the right brain brain area (g2, g4 and g6) of a brain area arranged in the left cerebral hemisphere (g1, g3, g5) is assigned to uniquely. The perfusion - image data sets are segmented, wherein brain - image data sets are generated, which only those picture elements of the perfusion - image data sets, the the brain (2) of the patient represent. In each of the brain - image data sets, n sets, whereby a m - ter part image data set only those pixels of the respective brain - image data set comprising a m - te of the n brain regions (g1 - g6), with m = 1.. n. per m - ter brain area (g1 - g6), by evaluation of all m -, which is of one or more sets of characteristic values determined after a predetermined evaluation method. Finally, there is an evaluation of the characteristic values of uniquely assigned to each other gerhirnregionen (g1 - g6) according to predetermined criteria for the comparison of the right and left cerebral hemisphere.
