Background, Motivation and Objective Tissue Doppler imaging (TDI) is widely used in clinical routine to assess regional myocardial motion/deformation. Typically, a high frame rate (HFR) can be achieved by narrowing down the field of view (FOV) to ~30° (only covering 1 cardiac wall). However, a wide FOV is required in some clinical applications to image the whole left ventricle (LV), reducing the frame rate. We previously proposed to use multi-line transmit beamforming (MLT) achieving HFR TDI and preserving a wide FOV (i.e. 90°sector) (MLT-TDI), thus avoiding any compromise. The aim of this study was to validate the MLT-TDI technique in-vivo and to investigate its performance in a clinical setting.
