HEART WALL STRAIN IMAGING

摘要

Ultrasound image processing system comprising means for acquiring ultrasound image data of the heart, means for forming a sequence of ultrasound images of the heart during a cardiac cycle and means for providing tissue velocity data of the heart wall, and further comprising means for estimating the time occurrence of a specific event related to heart strain for a point inside the heart wall. This system may comprise means for estimating the temporal variations of heart strain measured at a selected point inside the heart wall. This system may further comprise means for estimating the instants of occurrence of maximal and minimal variations of heart strain and their amplitudes from the measured temporal variations of heart strain at a selected point inside the heart wall and means for estimating the instants of temporal occurrences of the maximal and/or minimal variations of heart strain, along a line representing the heart wall.
