Field II Simulation and Coherence Factor Weighting for Multi-Angle Compound Plane Wave Imaging

In this article, we introduce a novel algorithm—Field II simulation of multi-angle compound plane wave imaging with coherence factor weighting. This algorithm operates on a weighted imaging principle and is designed to run directly within the Field II toolkit. By coherently compounding plane waves transmitted at multiple angles, the method generates high-resolution images with improved contrast and reduced speckle noise. The implementation typically involves defining plane wave transmission sequences, calculating backscattered signals, applying delay-and-sum beamforming, and computing coherence factors to weight the final image output. This technique has broad applications in medical imaging, particularly in ultrasound, where it enhances image quality and diagnostic accuracy. Notably, the algorithm is not limited to medical imaging; it can also be adapted for other image processing tasks such as robotic vision and object recognition, leveraging its robustness in coherence-based signal enhancement.
