Abstract
The number of signal lines connecting an ultrasound probe and an apparatus main body of an ultrasound diagnostic apparatus can be reduced while suppressing reduction of the maximum opening width of the ultrasound probe. A transducer array is conceptually divided into a plurality of center-side main transducers located on a center side of an arrangement, a plurality of first end-side main transducers located on a first end side of the arrangement with respect to the plurality of center-side main transducers, and a plurality of second end-side main transducers located on a second end side with respect to the plurality of center-side main transducers. A connection circuit is configured to include a first circuit connecting a transmission and reception circuit and the center-side main transducer, and a second circuit provided with a switch as a main transducer switching switch for switching a connection destination of the transmission and reception circuit between the first end-side main transducer and the second end-side main transducer.
