Method and system for detecting and analyzing heart mechanics

摘要

Method and apparatus for detecting and analyzing heart mechanical activity at a region of interest of a patient's heart are provided. The method comprises acquiring a time sequence of 2-dimensional X-ray images of a region of interest over at least part of a cardiac cycle; detecting coronary vessels in the X-ray images; tracking the coronary vessels through the sequence of images to identify movements of the coronary vessels; and analyzing the movements of the coronary vessels to quantify at least one parameter characterizing heart wall motion in the region of interest.

1. A method for detecting and analyzing heart mechanical activity at a region of interest of a patient's heart, comprising the following steps:
acquiring a time sequence of 2-dimensional X-ray images of said region of interest over at least part of a cardiac cycle; detecting coronary vessels in said X-ray images; tracking the coronary vessels through said sequence of images to identify movements of the coronary vessels according to the time sequence of 2-dimensional X-ray images taken over at least part of a cardiac cycle; analyzing the movements of the coronary vessels to quantify at least one parameter characterizing heart wall motion in said region of interest; and generating a strain graph of said region of interest representing contraction or expansion or both contraction and expansion over time through said at least part of the cardiac cycle.
