Comparison of ventricular geometry for two real time 3D ultrasound machines with three dimensional level set

This paper presents new results for segmentation of 3D ultrasound using a robust and smooth segmentation method based on a homogeneity-driven three dimensional level set algorithm. The segmentation was applied to echocardiographic data from healthy volunteers acquired with two 3D ultrasound machines based on matrix-phased array technology. A comparison of ventricular volumes and geometry is performed based on manual and automatic methods of segmentation. Results showed good agreement of the segmentation methods and the ultrasound machines for ventricular geometry and quantitative assessment of cardiac function.
