Background, Motivation and Objective Traditional ultrasound imagers suffer from a large data rate between their analog to digital converter (ADC) front-end and digital beamforming backend. This high a
Background, Motivation and Objective In quantitative echocardiography, a robust and accurate automatic segmentation of the left ventricle (LV) is important. Poor image quality and the rapid motion of
Background, Motivation and Objective Coded excitation can improve the signal-to-noise ratio (SNR) in medical ultrasound imaging.
Background, Motivation and Objective Flow Mediated Dilation (FMD) is widely used to assess the endothelial function by ultrasound. Ideally, both the brachial artery wall shear stress (stimulus) and di
Background, Motivation and Objective During neurosurgery, intraoperative imaging can serve to provide feedback on cerebrovascular hemodynamics and help monitor procedures such as the placement of flow
Background, Motivation and Objective The peak blood velocity is a parameter of high medical interest used, for example, in the determination of carotid stenosis grade. The standard approach, which typ
Background, Motivation and Objective Golay Complementary Sequence (GCS) can compensate the high attenuation of high-frequency ultrasound by elevating signal level with low range side lobe and low impl
Background, Motivation and Objective In color flow imaging (CFI), achieving robust flow detection in the presence of tissue motion remains a long-standing challenge to be properly addressed. Key to ta
Background, Motivation and Objective The twinkling artifact is a phenomenon that rapidly alternating color pixels behind a stationary strongly reflecting medium where an acoustic shadow is expected in
Background, Motivation and Objective The well-known non-linear effect of acoustic radiation pressure, present in front of an emitting ultrasonic transducer, results in a net force that pushes the tran
