Title:
ULTRASONIC DIAGNOSTIC DEVICE AND METHOD OF CONTROLLING ULTRASONIC DIAGNOSTIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/181597
Kind Code:
A1
Abstract:
An ultrasonic diagnostic device (1) includes: a vibrator array (2); a transmission unit (3) that transmits an ultrasonic pulse (FP) and an ultrasonic pulse (SP) the phases of which are inverted from each other from the vibrator array (2), a plurality of times, on the same scanning line; a reception unit (4) that acquires a reception signal from an output signal of the vibrator array (2); a quadrature detection unit (5) that acquires an IQ signal sequence by quadrature detection of the reception signal; a tissue velocity detection unit (6) that detects a velocity of a tissue inside a subject on the basis of the IQ signal sequence; a phase correction unit (7) that corrects a phase of the IQ signal sequence; a pulse inversion addition unit (8) that adds an IQ signal that corresponds to the ultrasonic pulse (FP) and an IQ signal that corresponds to the ultrasonic pulse (SP) using the corrected IQ signal sequence to acquire an added signal; and an image generation unit (10) that generates an ultrasonic image from the added signal.
