THREE-DIMENSIONAL PW (PULSED WAVE) SPECTRUM ULTRASONIC DIAGNOSTIC APPARATUS AND THREE-DIMENSIONAL PW SPECTRUM DATA GENERATING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a three-dimensional PW spectrum ultrasonic diagnostic apparatus and a three-dimensional PW spectrum data generating method.;SOLUTION: The three-dimensional PW spectrum ultrasonic diagnostic apparatus transmits a first PW Doppler ultrasonic signal and a second PW Doppler ultrasonic signal to an object using a two-dimensional array probe, receives a first PW Doppler response signal corresponding to the first PW Doppler ultrasonic signal, and a second PW Doppler response signal corresponding to the second PW Doppler ultrasonic signal, from the object, forms a three-dimensional sample gate using the received first PW Doppler response signal and second PW Doppler response signal, and generates three-dimensional PW spectrum data using the formed three-dimensional sample gate.;COPYRIGHT: (C)2011,JPO&INPIT
