<p>PROBLEM TO BE SOLVED: To provide an ultrasound diagnostic device which causes little voltage loss or power loss in comparison with a conventional device.SOLUTION: The ultrasound diagnostic device has at least one transmission circuit 10 for generating a transmission signal to be supplied to multiple ultrasonic transducers and a switching device for supplying the transmission signal to a selected ultrasonic transducer. The switching device includes a first coil to be electrically connected to at least one transmission circuit 10; a second coil magnetically coupled with the first coil to be electrically connected to the selected ultrasonic transducer; a third coil magnetically coupled with the first coli to be electrically connected to an ultrasonic transducer which is different from the selected ultrasonic transducer; a second short device magnetically coupled with the second coil to selectively short the second coil; and a third short device magnetically coupled with the third coil to selectively short the third coil.</p> |
