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.
