Abstract
For realization of an ultrasonic diagnostic apparatus capable of satisfactorily narrowing a beam width while suppressing an increase in the number of focus data, an ultrasonic diagnostic apparatus is designed to include an ultrasonic probe 10 that transmits or receives ultrasonic waves to or from a subject, a transmission unit 12 that supplies a driving signal to the ultrasonic probe 10, a reception unit 16 that handles a received signal sent from the ultrasonic probe 10, a unit 18 that reconstructs an ultrasonic image on the basis of a signal sent from the reception unit 16, and a unit 20 that displays the ultrasonic image. The ultrasonic diagnostic apparatus further includes an element selection unit 22 that selects a plurality of driving oscillatory elements, which constitutes an aperture through which ultrasonic waves are transmitted or received, from among a plurality of oscillatory elements that constitutes the ultrasonic probe 10 and transforms ultrasonic waves into electric signals or vice versa. The element selection unit 22 groups the plurality of driving oscillatory elements into a plurality of sets, each of which includes one driving oscillatory element or a plurality o…
