Abstract: A transmission circuit transmits an ultrasonic signal from an ultrasonic vibrator by driving a terminal voltage of the ultrasonic vibrator using a first pulse signal and then further driving the terminal voltage using a second pulse signal having an opposite phase to the first pulse signal. At least one of a pulse number of the second pulse signal and a pulse level of the terminal voltage is arbitrarily set.

Abstract: An ultrasound diagnostic device includes: a transmission pulser that applies a driving pulse output signal to an ultrasonic transducer so as to cause the ultrasonic transducer to irradiate ultrasound; and a trigger signal generator that generates a trigger signal that controls the transmission pulser to output the driving pulse output signal. The trigger signal generator adds, to the trigger signal in a predetermined term after completion of a driving term of the ultrasonic transducer, a plurality of trigger pulses that control an amplitude of an ultrasonic transducer output signal generated upon completion of the driving term so as to attenuate gradually. With this configuration, a free vibration of the ultrasonic transducer in a transient response can be suppressed with the minimum number of circuit materials.

Abstract: A micromachined ultrasonic transducer (MUT) circuit, which has a MUT with a MUT membrane that can vibrate back and forth to transmit an ultrasonic wave, electrically controls the movement of the MUT membrane by controllably transferring energy to the MUT membrane, thereby allowing the MUT membrane to transmit substantially any desired ultrasonic wave.
