An exemplary imaging apparatus includes a wave generator for generating a wave in an article; a detector for detecting a wave in the article; and a processor which: forms a matched filter based on a response of the article to a wave propagated through the article; directs the wave generator to generate a wave at a plurality of generation positions; directs the detector to detect a motion of the article at a plurality of detection positions; forms a scan data set from the detected motion of the article; multiplies the scan data set by the matched filter to produce a compensated data set; and coherently sums data points in the compensated data set to produce a focused image.
