Two-dimensional and three-dimensional strain mapping for uterine contractions

摘要

Some embodiments are directed to a method for quantitative visualization of uterine strain. The method includes receiving a number of 2D or 3D image frames acquired via an imaging technique and selecting a number of confidential points, determining the orientation of the uterus using the confidential points, selecting a region of interest, generating a grid of tracking points inside the region of interest and tracking and estimating the displacement of tracking points between frames. From a varying distance between each couple or set of tracking points, a strain is calculated. The orientation of the grid of tracking points and of the calculated strain is dependent on the determined orientation of the uterus.
