A method for plane wave (PW) ultrasound imaging is disclosed. The method includes transmitting a PW of a plurality of PWs at a transmission angle from a plurality of ultrasound transducers to a target, receiving a radio frequency (RF) echoes subset of a plurality of RF echoes at a non-...
Plane-wave imaging (PWI) is an interesting technique for increasing frame rate in medical ultrasound imaging, but it suffers from poor image quality. To ov... M Hashemseresht,S Afrakhteh,H Behnam - 《Biomedical Signal Processing & Control》 被引量: 0发表: 2022年 A Joint Delay-and-Sum ...
ultrasonography is only limited by the time required for a wave to make a two-way travel. Theoretically, frame rates up to 15,000 Hz can thus be attained for a 5-cm imaging depth [2]. Recent studies indicate the growing emergence of ultrasound plane wave imaging (PWI). This technique ha...
In this paper, we extend these lines of work to the case of ultrasound plane wave imaging and evaluate the obtained performance from various numerical simulations. 展开 关键词: Probes Ultrasonic imaging Image reconstruction Biomedical imaging Telecommunications Frequency modulation 被引量: 4 ...
The Eigenspace-based beamformers, by orthogonal projection of signal subspace, can remove a large part of the noise, and provide better imaging contrast upon the minimum variance beamformer. However, wrong estimate of signal and noise component may bring dark-spot artifacts and distort the signal...

EAC methods typically employ either one-dimensional (1D) arrays that can only control the US beam in the azimuthal direction (i.e. parallel to the imaging plane) or two-dimensional (2D) arrays that can control the US beam in both the azimuthal and elevational directions (the latter being ...
Diverging wave mode with multiple virtual sources The 2-D sparse arrays that were tested in DW imaging mode are the same arrays that were described above for focused imaging (IV.C.1). In particular, the optimized 2-D sparse array (opti256) was shown capable of producing a focused beam wi...
