    摘要: An ultrasonic apparatus for scanning an image field of a subject extending in substantially opposite directions from the middle of said field to lateral extremes of said field with beams of ultrasound which are transmitted and received in a pattern in which the beams are spatially adjacent to each other over said image field. This apparatus has means for minimizing multipath artifacts, comprising means for sequentially transmitting and receiving ultrasonic beams in successive beam directions along which the consecutively transmitted and receive beams are substantially spatially separated, and in an alternate manner. This means may include means for sequentially transmitting and receiving beams in successive beam directions that are divergent from a first beam direction located at a first location in said image field alternately each side of the first beam direction; and/or means for sequentially transmitting and receiving beams in successive beam directions that are convergent from two opposite beam directions alternately towards the center of said image field.
