Practically applied techniques for ultrasonic biomedical imaging employ delay-and-sum
(DAS) beamforming which can resolve two objects down to 2.1 λ within the acoustic Fresnel …

Plane wave imaging (PWI), a typical ultrafast medical ultrasound imaging mode, adopts
single plane wave emission without focusing to achieve a high frame rate. However, the …

The beamforming performance has a large impact on image quality in ultrasound imaging.
Previously, several adaptive weighting factors including coherence factor (CF) and …

The use of particle localisation and tracking algorithms on Contrast Enhanced Ultrasound
(CEUS) or other ultrasound mode image data containing sparse microbubble (MB) …

Minimum Variance (MV) beamforming is known to improve the lateral resolution of
ultrasound images and enhance the separation of isolated point scatterers. This paper aims …

Due to the severe lateral lobe artifact by coherent plane-wave compounding (CPWC) and
the low signal-to-noise ratio of radiofrequency (RF) data collected from the plane wave, the …

Ultrasonic synthetic aperture focus techniques (SAFTs) using less than the total number of
available array elements to transmit (“sparse” transmissions) have been recently used in …

This article presents improvements to ultrasonic imaging of solid platelike structures using
the minimum-variance distortionless response (MVDR) beamforming processor. The primary …

Objective: This paper aims to develop a method for achieving micrometre axial scatterer
localization for medical ultrasound, surpassing the inherent, pulse length dependence …

Plane wave compounding (PWC) is a valid method for ultrafast ultrasound imaging. Its
imaging quality depends on the beamforming method. The coherence factor (CF) and …
