Abstract: A method and device for interpreting and processing medical ultrasound and other video images. The mix of reflection coefficients in pixel windows is measured by determining the range and distribution of pixel gray scale values to establish an "echoic texture," which can be scaled or used to color the image to facilitate identification of tissue characteristics. The image may also be processed by a variety of enhancement methods including processes for contour following, edge and contrast enhancement, smoothing and noise abatement. Processing times are reduced by limiting certain processes to pixels established by a line drawing in machine memory identifying pixel patterns characteristic of element edges. The results of processing from consecutive images may be compared and aberrant results may be corrected.
