要約
(EN)
The disclosed invention accurately acquires environmental sound velocity without bringing about a drop in processing or diagnostic efficiency. Each element of an ultrasonic probe is driven on the basis of a prescribed transmission delay time, and ultrasonic wave transmission is carried out, the focus of which is focused at a prescribed transmission focus point. An actual focus point or an effective region including said focus point is determined according to the ultrasonic transmission to the transmission focus point, on the basis of a reception signal received by each element according to the reflected waves reflected due to the ultrasonic wave transmission to the transmission focus point.
