Automatic Real-time Left Ventricular Tracking in 3D Echocardiography: Using probabilistic contour tracking and sequential state estimation algorithms
Orderud, Fredrik (Master thesis, 2006)This thesis presents a new framework for automatic real-time left ventricular (LV) tracking in 3D+T echocardiography. The framework enables usage of existing biomechanical deformation models for the heart, with nonlinear ... -
Practical use of Block-Matching in 3D Speckle Tracking
Nielsen, Karl Espen (Master thesis, 2009)In this thesis, optimizations for speckle tracking are integrated into an existing framework for real-time tracking of deformable subdivision surfaces. This is employed in the segmentation of the the left ventricle (LV) ... -
Real-time segmentation of 3D echocardiograms using a state estimation approach with deformable models
Orderud, Fredrik (Doctoral Theses at NTNU, 1503-8181; 2010:55, Doctoral thesis, 2010)Cardiac ultrasound, or echocardiography, is considered to be the quickest and most cost effective imaging modality for assessment of cardiac function. The modality is unique in that it allows for real-time imaging of the ... -
Segmentation of Right Ventricle in 3D Ultrasound Recordings
Engås, Asbjørn Breivik (Master thesis, 2008)This thesis presents segmentation of the right ventricle of the heart in real-time tracking of 3D ultrasound recordings. A simple deformable model for the right ventricle is developed based on statistical data from manual ...
