The paper develops computer-vision methods to automatically analyze uterine mucosal peristaltic waves from cine-MR image sequences, aiming to provide objective quantitative measurements for use in a larger clinical study. Using optical flow (and also mentioning block matching), the authors report that optical-flow representations are an adequate basis for computing quantitative and qualitative measures of uterine peristalsis. A major limitation stated is that the method is not yet automated for larger sample numbers, with ongoing work focused on scaling the approach. Relevance to endometriosis: the introduction explicitly links endometriosis to female infertility and describes the uterine lining/endometrial function context, though the study’s main focus is algorithmic quantification of uterine peristalsis from cine-MRI rather than endometriosis biology.

Abstract One of the major causes for female infertility is identified by endometriosis, which is a disorder of the endometrial function and tissue lining of the uterus. The aim of this research is to develop methods to enable the automated analysis of the peristaltic waves of the uterus mucosa from sequences of MRI images. Automatic methods are needed within the framework of a larger clinical study to provide objective measurements. In this contribution we show that computer-vision methods like block matching and the optical flow can be successfully used for these purposes. In particular the optical flow of the analyzed sequences represents an adequate basis for the computation of quantitative and qualitative measures of the peristaltic waves. Ongoing research aims at automatizing this method for a larger sample number. Preview Unable to display preview. Download preview PDF.
