1. A method comprising:
obtaining a set of ultrasound signals at successive times at a plurality of spatial points within biological tissue;
decomposing the set of ultrasound signals into multiple terms of a sum, wherein the multiple terms include respective spatial component image factors and respective temporal component signal factors, wherein spatial component images corresponding to the spatial component image factors are mutually orthonormal, and wherein temporal component signals corresponding to the temporal component signal factors are mutually orthogonal;
determining sharpened spatial images for each of the spatial component images; and
generating a processed image including a bilinear combination of the sharpened spatial images.
