Application of ultrasound to remove thrombi from the Left ventricular assist device

Due to limited number of donor hearts and stringent eligibility criteria for heart transplant the Left ventricular assist device (LVAD) has emerged as a relevant treatment option for heart failure. Occlusion in the form of a thrombus (blood clot) is a feared complication associated with the LVAD. The ability of ultrasound to result in effects...

Database guided detection of anatomical landmark points in 3D images of the heart

Automated landmark detection may prove important for the examination and automatic analysis of real-time three-dimensional (3D) echocardiograms. By detecting 3D anatomical landmark points, the standard anatomical views can be extracted automatically in 3D ultrasound images of left ventricle, for better standardization and objective diagnosis....

3D Transesophageal echocardiography using a fast-rotating transducer

Echocardiography is a diagnostic modality which is widely used in cardiology, using ultrasound to image the living heart and assess its physiological function. Three-dimensional echocardiography surpasses the visual limitations of conventional echocar-diography, offering a three-dimensional perspective of the heart. Traditional techniques for...
