Computation of the ejection ratio of the ventricle from echocardiographic image sequences
Abstract
Our contribution deals with the automatic computation of the ventricle volume ratio of the human heart at the end-systolic and the end-diastolic phases based on echocardiographic image sequences. The proposed method includes the use of an application-specific designed median filter for noise reduction in echochardiographic images, the detection of the end-systolic and end-diastolic phases based on the analysis of motion vector fields, and the segmantation of the ventricle using a region growing method. The presented simulation results have been compared with manually obtained measurements of the ejection ratio.
