1. A system for use with a transducer array, the transducer array configured to deliver energy to a tissue region, the system comprising: a processor circuit configured to: obtain, using the transducer array, information indicative of the delivered energy reflected from the tissue region; form respective input matrices representative of the obtained information indicative of the energy reflected from the tissue region, the respective input matrices including information corresponding to a spatial dimension and a temporal dimension, 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; perform respective singular value decompositions on the respective input matrices to obtain respective sets of singular values corresponding to respective sets of singular vectors; obtain 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 determine a characteristic, or construct an image, of at least a portion of the tissue region.
