Wide-angle Tissue Doppler Imaging at High Frame Rate Using Multi-line Transmit Beamforming: An Experimental Validation In-Vivo KU Leuven
Color tissue Doppler imaging (TDI) is a well-established methodology to assess local myocardial motion/deformation. Typically, a frame rate of ∼ 200 Hz can be achieved by imaging a narrow sector (∼ 30°, covering one cardiac wall) at moderate line density, using a dedicated pulse sequence and multi-line acquisition. However, a wide angle field-of-view is required in some clinical applications to image the whole left ventricle, which implies a ...
