This paper describes an original strategy for an automatic quantitative estimation of the regional myocardial wall thickening from segmentation of echocardiographic images. Our method is decomposed in two steps : first, we have developed a user-friendly computer software of segmentation to extract the myocardial wall in each image of the sequence. Secondly, the software automatically computes the regional wall thicknesses evolution for a cardiac sequence. The results are shown on regional diagrams. Furthermore, the percent systolic wall regional thickening is computed. This quantitation ofregional wall thickening by ultrasound imaging should be very helpful for physicians in the assessment ofthe cardiac contraction function.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
