A method has been devised to characterize tissue using the video image of an ultrasonic sector scan. An image processing computer developed for this purpose utilizes an array processor to perform spectral analysis on a portion of a digital video ultrasound image. The spectral analysis provides an indication of the structure of the tissue that diffracts and reflects the ultrasound beam. The amount of detail is not sufficient to determine the actual tissue structure but the result is detailed enough to provide a comparison with other tissue images. A measure based on covariances, called difference cross-covariance, is used for comparison. Results with normal and diseased ventricular septa suggest that the technique can be used to ascertain the presence of differences in the structures of two tissues.
