Abstract Delay-and-sum (DAS) is the most widespread digital beamformer in high-frame-rate
ultrasound imaging. Its implementation is simple and compatible with real-time applications …

Abstract Background and Objective Computational ultrasound imaging has become a well-
established methodology in the ultrasound community. Simulations of ultrasound sequences …

Medical ultrasound imaging requires recurring use of elementary principles, namely, the
choice of the transducer, the design of the emitted waves and their wavefronts (eg focused …

Abstract Background and Objective: Computational ultrasound imaging has become a well-
established methodology in the ultrasound community. In the accompanying paper (part I) …

Before embarking on a series of in vivo tests, design of ultrasound-flow-imaging modalities
are generally more efficient through computational models as multiple configurations can be …

Four-dimensional ultrasound imaging of complex biological systems such as the brain is
technically challenging because of the spatiotemporal sampling requirements. We present …

Implementation of a high-frequency ultrasound (HFUS) beamformer is computationally
challenging because of its high sampling rate. This article introduces an efficient …

Color Doppler by transthoracic echocardiography creates two-dimensional fan-shaped
maps of blood velocities in the cardiac cavities. It is a one-component velocimetric technique …

Doppler ultrasound is the premier modality to analyze blood flow dynamics in clinical
practice. With conventional systems, Doppler can either provide a time-resolved …

Color Doppler imaging (CDI) is the modality of choice for simultaneous visualization of
myocardium and intracavitary flow over a wide scan area. This visualization modality is …
