Computation of the Ejection Ratio of the Ventricle from Echocardiographic Image Sequences

摘要

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 echocardiographic images, the detection of the end-systolic and end-diastolic phases based on the analysis of motion vector fields, and the segmentation of the ventricle using a region growing method. The presented simulation results have been copared with manually obtained measurements of the ejection ratio.
