摘要：
Apparatus or techniques can include obtaining information indicative of energy, such as ultrasonic energy, reflected from a tissue region, forming respective input matrices representative of the obtained information, the input matrices respectively comprising an ensemble-of-interest and at least one ensemble corresponding to a spatial location nearby a spatial location corresponding to the ensemble-of-interest, performing respective singular value decompositions on the respective input matrices to obtain respective sets of singular values corresponding to respective sets of singular vectors, obtaining respective output matrices including weighting a respective projection of a respective ensemble-of-interest onto at least one of the singular vectors included in a respective set of singular vectors, and, using the respective output matrices, at least one of determining a characteristic, or constructing an image, of at least a portion of the tissue region.
