Title:
METHOD FOR OBTAINING DISPLAY OF SIZE AND DIRECTION OF FLOWING REFLECTOR AND COHERENT IMAGING SYSTEM
Document Type and Number:
Japanese Patent JPH05228147
Kind Code:
A
Abstract:
PURPOSE: To provide a method and a device for determining a display of a size and a direction of a flowing reflector, by which the flowing speed in a range direction can be measured by using a doppler method, simultaneously with the measurement of the flow in a lateral direction to the range by using a correlation method. CONSTITUTION: A phasing array sector scan supersonic imaging device simultaneously generates the transmitting supersonic pulses toward the fluidized reflector 38, and samples the received beams 35, 36 and 37 to the same. A speed of flow in a lateral direction to a range R is measured by using the correlation method, and a speed of flow in a range direction is simultaneously measuring by using a doppler method to the same. By executing the cross-correlation of a set of the data obtained by the multi-beam collection in both of the range direction and the lateral direction to the range R, a B-scan image indicating both of the size and direction of the fluidized reflector 38, can be obtained.
