Method for characterizing perfusion abnormalities by means of fractal analysis of the interface region
The present invention relates to a method for characterizing perfusion abnormalities in tissue by means of fractal analysis (FA) of at least one part of an interface region between adequately and abnormally perfused tissue comprising the steps of providing an imaging dataset of perfusion imaging; wherein said imaging dataset visualizes the at least one part of the interface region; optional pre-processing of said imaging dataset; applying fractal analysis to the imaging dataset; wherein said fractal analysis provides at least one fractal parameter, preferably fractal dimension (FD), of the at least one part of the interface region.
MEDICAL INFORMATION PROCESSING APPARATUS AND MEDICAL INFORMATION PROCESSING METHOD
A medical information processing apparatus according to an embodiment includes processing circuitry. The processing circuitry acquires a first index value obtained based on fluid analysis that is performed based on an image including a blood vessel of a subject, the first index value being related to blood flow at each of positions in the blood vessel. The processing circuitry acquires external information including a second index value related to blood flow at each of the positions in the blood vessel. The processing circuitry changes one of an arrangement direction of index values in a first graph and an arrangement direction of index values in a second graph in accordance with the other one of the arrangement directions. The processing circuitry displays the first graph and the second graph on a display unit such that the arrangement directions of the index values match each other.
