Goal: In this study, we demonstrate that a deep neural network (DNN) can be trained to reconstruct high-contrast images, resembling those produced by the multistatic Synthetic Aperture (SA) method using a 128-element array, leveraging pre-beamforming

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

The recent development of high-frame-rate (HFR) imaging/Doppler methods based on the transmission of plane or diverging waves has proposed new challenges to echographic data management and display. Due to the huge amount of data that need to be proce

The use of wide beams in transmission and parallel beamforming in reception allows increasing the frame rate of ultrasound images. Any misalignment between the transmitted beams and the received lines determines spatial discontinuities that appear as

High-frame-rate (HFR) speckle-tracking echocardiography (STE) assesses myocardial function by quantifying motion and deformation at high temporal resolution. Among the proposed HFR techniques, multiline transmission (MLT) and diverging wave (DW) imag

In a recently proposed high frame rate (HFR) Vector Flow Imaging (VFI) method, the displacements between consecutive beamformed radiofrequency (RF) frames are estimated from the corresponding phase shifts recorded in the frequency domain. Although su

In range-Doppler ultrasound applications, the velocity of a target can be measured by transmitting a mechanical wave, and by evaluating the Doppler shift present on the received echo. Unfortunately, detecting the Doppler shift from the received Doppl

Standard scanned Color Flow Imaging (CFI) is a common blood flow visualization modality. Despite being introduced more than 30 years ago, this technique is still hampered by the conflicting requirements for either a good image quality or a high frame

High frame rate (HFR) imaging methods based on the transmission of defocused or plane waves rather than focused beams are increasingly popular. However, the production of HFR images poses severe requirements both in the transmission and the reception
