ULTRASONIC THREE-DIMENSIONAL IMAGE PICKUP DEVICE

摘要

PURPOSE:To realize three-dimensional ultrasonic image pickup of high pickup speed and high resolution by forming simultaneously a number of three- dimensional reception beams being uniform in sensitivity. CONSTITUTION:In a three-dimensional reception focusing means 4, a plurality of three-dimensional reception beams in directions at equal angles to one direction of transmission are formed simultaneously. Since the three-dimensional beams being uniform in sensitivity can be formed in large numbers simultaneously in this constitution, three-dimensional ultrasonic image pickup of high pickup speed and high resolution can be realized.
