Ultrasound contrast plane wave imaging

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2012
Monitoring the accumulation of microbubbles within tissue vasculature with ultrasound allows both molecular and perfusion imaging. Unfortunately, conventional imaging with focused pulses can destroy a large fraction of the microbubbles it is trying to follow.

Plane-wave phase-coherence imaging for NDE

NDT and E International, 2017
Abstract In ultrasound imaging with arrays the frame rate is limited by the number of insonifications of the inspected medium. In the limit, a single omnidirectional or plane wave insonification (OWI or PWI, respectively) would provide the maximum frame rate.

Extended Aperture Image Reconstruction for Plane-Wave Imaging

SSRN Electronic Journal, 2023
B-mode images undergo degradation in the boundary region because of the limited number of elements in the ultrasound probe. Herein, a deep learning-based extended aperture image reconstruction method is proposed to reconstruct a B-mode image with an enhanced boundary region.

Machine learning for plane wave imaging

Proceedings of the Annual British Conference on Non-Destructive Testing, 2023
Phased array ultrasonics have enabled the recording of an ever-increasing amount of data from the inspection targets. With the latest advancements in total-focusing method with plane wave imaging the amount of data has increased exponentially when compared to conventional ultrasonic methods.
