This paper is an extension of our ISBI 2011 work, where we proposed a novel variational approach to estimate dense myocardial velocity fields from 4D ultrasound (4DUS). In this paper, we present a thorough performance evaluation of our method by comparing it with the primary method of record, which relies on cross-correlation. Our comparative performance evaluation uses several data sources, including...
This paper presents a method for the computation of 3D flow in 4D (3D spatial+time) Transesophageal Echocardiography (4D TEE). 4D echocardiography is the only modality that allows real-time 3D imaging of the heart, at rates that are sufficiently high to characterize the very fast motion of key anatomical structures, such as the mitral and aortic valves or the left ventricle. The method described in...
