Abstract
A system and method includes reception of a first image of a blood vessel, reception of a second image of the blood vessel, determination of a first size of a region of the blood vessel based on the first image, determination of a second size of the region of the blood vessel based on the second image, and calculation of a parameter of the blood vessel based on the first size and the second size.
Claims16
A system comprising:
- an interface configured to receive a first plurality of images of a blood vessel, and to receive a second plurality of images of the blood vessel;
- and
- a storage device configured to store program code executable by an image data processor to cause the image data processor to:
- determine a first plurality of respective sizes of a region of the blood vessel based on respective ones of the first plurality of images;
- determine a second plurality of respective sizes of a region of the blood vessel based on respective ones of the second plurality of images;
- calculate respective vessel contraction/expansion energy ratios based on at least one of the first plurality of respective sizes and at least one of the second plurality of respective sizes, the respective vessel contraction/expansion energy ratios each representing a ratio of an integral across multiple time regions for a duration associated with systole to the integral across multiple time regions for a duration associated with diastole;
- combine the respective vessel contraction/expansion energy ratios to form a universal ratio representing a summation of a plurality of respective products, each of the respective products being a product of each of the respective vessel contraction/expansion energy ratios multiplied by at least one calculation coefficient over increments of the blood vessel region;
- analyze the respective vessel contraction/expansion energy ratios to characterize a presence of at least one of a cardiac functional abnormality and an arrhythmia;
- display a result of the analysis on a display device of a terminal in communication with the image data processor, the display result including at least one of a mapping of an artery tree and a cardiac coronary artery matrix;
- and
- the artery tree mapping and the cardiac coronary artery matrix including an identification of a potential pathological position of at least one specific myocardial ischemic location in at least one of an artery and an artery branch, the myocardial ischemic location position based on a result of the analysis.
