ABSTRACT:
A method and apparatus for representing ultrasonic echo signals arriving in polar coordinates which are obtained by means of a sector scan technique and which are intermediately stored for the purpose of subsequent display conforming to television standards alternately supply the echo signals to one of at least two complete image memories having respective two-dimensional matrix memory formats. The image memories operate an alternating buffer memories and eliminate the need for conventionally employed vector memories and horizontal memories while nonetheless permitting complete representation of the ultrasonic scans in the form of television images.
