A system and method for center point trajectory mapping includes a computer readable storage medium having stored thereon a computer program comprises instructions, which when executed by a computer, cause the computer to acquire a first plurality of images, each image comprising a masked portion. The instructions also cause the computer to locate a center point of the masked portion in each of the plurality of images and to plot a map based on variances in position of the center points from each other. The instructions further cause the computer to display the map on a display.

System and method for center point trajectory mapping

A computer implemented method of mapping of multiple regional center point trajectory movements of cavity walls is provided in which images are acquired and a region-of-interest is identified in each of the images. The region-of-interest is divided into a plurality of distinct regions and a regional center point for each of the regions is located in the images. For each regional center point, a center point trajectory is determined based on variances in position of the center points from each other in the images. The center point trajectory of each regional center point is decomposed into radial and circumferential components so as to isolate radial component of the center point trajectory for each regional center point in each of the images and radial motion versus time curves are displayed for each regional center point based on the determined radial component for each regional center point in each of the images.
