Quantification of Right and Left Ventricular Function With Real-Time Three-Dimensional Ultrasound

Abstract

This paper presents a study for validation of real-time three-dimensional ultrasound as a diagnostic tool in patients with primary pulmonary hypertension. Dynamic analysis of the heart is performed via qualification of right and left ventricle volumes. Segmentation of ventricular cavities is performed via a deformable-model for a set of denoised frames spread over an entire cardiac cycle. Spatio-temporal denoising is carried out by brushlet analysis that has been optimized by incorporating space and time coherence in texture characterization. Quantitative measures for right and left ventricular ejection fraction are compared to clinical MRI of the same patients.
