SYSTEM AND METHOD FOR DETERMINING MYOCARDIAL PERFUSION PATHOLOGY Russian patent published in 2019 - IPC A61B5/55 G06T7/10 A61B5/26 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine, specifically to the medical imaging of the heart. Medical imaging device comprises a system and a software module for implementing a method for determining the pathology of myocardial perfusion, in which the steps of the method to be performed are converted into the program code of the software module, wherein the program code is implemented in the memory unit of the control unit of the medical imaging device and can be executed by the processor unit of the control unit of the medical imaging device. Method comprises steps of: delineating contours of a selected part of the heart of the subject of interest in a plurality of medical images and segmenting the selected part into a plurality of segments; measuring perfusion intensities in selected positions of the myocardial image from the plurality of medical images and assigning an index representing the order for obtaining each of the medical images corresponding to the measured perfusion intensities at the positions of the myocardial image in order to obtain the perfusion intensity curves for each of the selected positions of the myocardial image; calculating an index number indicative of a spatio-temporal perfusion inhomogeneity or perfusion dephasing among at least a subset of myocardial segments of the plurality of myocardial segments, wherein the subset of myocardial segments includes a plurality of myocardial segments, based on the obtained perfusion intensity curves (60).

EFFECT: invention can be used to determine the pathology of myocardial perfusion.
