Requirements and Hardware Limitations of High-Frame-Rate 3-D Ultrasound Imaging Systems
Applied Sciences, 2022 The spread of high frame rate and 3-D imaging techniques has raised pressing requirements for ultrasound systems. In particular, the processing power and data transfer rate requirements may be so demanding to hinder the real-time (RT) implementation of ...

Estimating the mechanical energy of histotripsy bubble clouds with high frame rate imaging. [PDF]
Phys Med Biol, 2021 Mechanical ablation with the focused ultrasound therapy histotripsy relies on the generation and action of bubble clouds. Despite its critical role for ablation, quantitative metrics of bubble activity to gauge treatment outcomes are still lacking. Here,

iMAP Beamforming for High-Quality High Frame Rate Imaging [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2019 We present a statistical interpretation of beamforming to overcome limitations of standard delay-and-sum (DAS) processing. Both the interference and the signal of interest are viewed as random variables and the distribution of the signal of interest is exploited to maximize the a-posteriori distribution of the aperture signals.

High Frame-Rate Cardiac Ultrasound Imaging with Deep Learning [PDF]
International Conference on Medical Image Computing and Computer-Assisted Intervention, 2018 Cardiac ultrasound imaging requires a high frame rate in order to capture rapid motion. This can be achieved by multi-line acquisition (MLA), where several narrow-focused received lines are obtained from each wide-focused transmitted line. This shortens the acquisition time at the expense of introducing block artifacts. In this paper, we propose a data-
