    • PURPOSE: An ultrasonic wave image diagnosis device capable of minimizing an image artifact of a teeth shape and a diagnosis method thereof are provided to minimize an image artifact of a teeth shape in an ultrasonic wave image caused by a spike voltage generated from a switching operation about a bias voltage of a high voltage multiplexer. CONSTITUTION: A probe(320) converts a pulse of an electronic signal into an ultrasonic signal through one or more transducer elements. A multiplexer(330) successively selects at least one of a plurality of transducer elements. A controlling unit(340) transfers a scan line corresponding to line density about the transducer elements. The controlling unit executes switching about different bias voltage by every pulse repetition frequency(PRF) in movement of the scan line.

    • PURPOSE: An ultrasonic wave image diagnosis device and a diagnosis method thereof are provided to remove a spike voltage generated by switching operation about first power and second power applied to a high voltage multiplexer. CONSTITUTION: A pulse generating unit(310) generates a pulse of an electric signal. A transducer(320) converts the generated pulse into an ultrasonic wave signal. A multiplexer (330) selects a channel corresponding to an element of the transducer. The multiplexer performs switching operation about supplied different voltages. A dummy multiplexer (340) supplies an output signal of the multiplexer and an inverted signal by the switching operation and inverted switching operation to an output terminal of the multiplexer in the switching operation.
