METHOD FOR DETERMINING HOMOGENEITY OF ATHEROSCLEROTIC PLAQUE STRUCTURE Russian patent published in 2016 - IPC A61B8/08 

FIELD: medicine.

SUBSTANCE: invention relates to functional diagnosis in cardiology, and can be used to evaluate homogeneity of structure of atherosclerotic plaque in carotid arteries or other large and medium-presence in patients with atherosclerotic lesions of arteries. Series of sequenced ultrasonic image frames of an atherosclerotic plaque in a longitudinal section of an artery over one cardiac cycle is obtained. Performing contouring of base and surface of plaque on one of initial training and selection by contour lines of three segments - distal, proximal and central. Estimating motion parameters assigned plaque surface segments relative to base period of cardiac cycle by determining tangential velocity plaques segment motion and/or speed changes of shear deformation segment plaques followed by plotting measured speeds from time. When a segment of collinear curves of plaque is obtained, conclude a homogeneous structure of plaque.

EFFECT: method enhances diagnostic accuracy due to objectification of interpretation of information received on surface of plaque motion relative to its base.
