ULTRASONIC DIAGNOSTIC DEVICE AND ULTRASONIC IMAGE GENERATION METHOD

摘要

There are provided an ultrasonic diagnostic device and an ultrasonic image generation method in which the direction of a beam formed in a subject is not changed even if at least one of set sound speeds used in transmission focusing processing and reception focusing processing is changed. When at least one of the set sound speeds used in the transmission focusing processing and the reception focusing processing has been changed by a set sound speed changing unit, a focusing processing correction unit corrects a delay of at least one of the transmission focusing processing and the reception focusing processing based on the changed set sound speed such that the direction of the beam formed in the subject is not changed.

主权项

1. An ultrasonic diagnostic device that transmits an ultrasonic wave toward a subject from an ultrasonic probe and generates an ultrasonic image based on obtained reception data, comprising:
a transmission and reception unit that performs at least one of transmission focusing processing and reception focusing processing in a desired steering direction; a set sound speed changing unit that changes at least one of set sound speeds used in the transmission focusing processing and the reception focusing processing; and a focusing processing correction unit that corrects a delay of at least one of the transmission focusing processing and the reception focusing processing based on the set sound speed when the set sound speed has been changed by the set sound speed changing unit.
