Abstract
A measuring apparatus for an ultrasonic velocity in a region of interest within a medium includes an array transducer, and a velocity measuring circuit. The transducer is constructed of a plurality of transducer elements which are subdivided into at least first and second transmitting sections and first and second receiving sections with having a distance. First and second ultrasonic beams are emitted from the first and second transmitting sections to the ROI under the condition that the transmitting beam axis is intersected by the receiving ultrasonic beam axis. Then, the first and second receiver sections receives in total four echoes reflected from four corners of the ROI. The velocity measuring circuit calculates the propagation time of the ultrasonic beams and finally the ultrasonic velocity based upon the propagation time.
