SYSTEM AND METHOD FOR ACCELERATED CLUTTER FILTERING IN ULTRASOUND BLOOD FLOW IMAGING USING RANDOMIZED ULTRASOUND DATA

摘要

Described here are systems and methods for ultrasound clutter filtering to produce images of blood flow in a subject. In general, the clutter filtering is based on a singular value implementation, such as an accelerated singular value decomposition (“SVD”). In one example, the singular value-based clutter filtering can be accelerated by implementing a randomized SVD (“rSVD”). In another example, the singular value-based clutter filtering can be accelerated by implementing a randomized spatial downsampling. In still another example, singular value-based clutter filtering can be accelerated by implementing both an rSVD and a randomized spatial downsampling.
