Parallel beamforming is frequently used to increase the acquisition rate of medical ultrasound imaging. However, such imaging systems will not be spatially shift invariant due to significant variation across adjacent beams. This paper investigates a few methods of …

This paper investigates a few methods of parallel beamforming that aims at eliminating this flaw and restoring the shift invariance property. The beam-to-beam variations occur because the transmit and receive beams are not aligned.

In this work, we experimentally evaluated the performance of parallel beamforming for STL-SWEI using fixed or multiple transmit focus. By imaging tissue-mimicking phantoms, we found that parallel beamforming improved the focal zone elastographic …

Implementing parallel beamforming algorithms in situ on distrib-uted array systems holds the potential to provide increased performance and fault tol-erance at a lower cost. This paper compares three parallel algorithms for distributed ar-rays in terms of execution throughput, result latency, scaled speedup, and parallel effi-ciency. 1.

2021年11月9日 · The proposed work aims to design a field-programmable gate array (FPGA)-accelerated parallel beamforming core for medical US sector imaging systems. This architecture supports up to 128 channels and forms 28 beams per plane wave transmission in parallel.

To increase the frame rate, parallel beamforming is a commonly used technique for fast cardiac imaging. Conventionally, a 4 multiple-line-acquisition (4MLA) system increases the frame rate by a...

Ultrasound images generated using conventional parallel beamforming contains stationary stripes due to beam-to-beam variations across adjacent beams. Such an imaging system is thus shift variant. This paper investigates a method which eliminates this flaw and restores the shift invariant property.

To increase the frame rate, parallel beamforming is a commonly used technique for fast cardiac imaging. Conventionally, a 4 multiple-line-acquisition (4MLA) system increases the frame rate by a factor of 4, making use of a broadened transmit beam to reduce block-like artifacts.
