PROCESSING METHOD FOR ULTRASONIC IMAGING SIGNAL AND ULTRASONIC DIAGNOSTIC DEVICE

摘要

PROBLEM TO BE SOLVED: To display blood flow velocity even by a contrast harmonic imaging method. SOLUTION: In the processing method for ultrasonic imaging signals, ultrasonic pulse signals are transmitted to an examinee body to which an ultrasonic contrast medium is administered and harmonic B mode images are formed on the basis of obtained echo reception signals. A fundamental wave component (f) and a higher harmonic component (2f) are separated and extracted from the echo reception signals and both extracted signals are displayed in an identifiable form on a same ultrasonic tomographic surface.
