An ultrasonic apparatus for transmitting ultrasonic waves and receiving reflection waves from an examination subject for display is used in a blood vessel with a catheter for two-dimensional imaging and three-dimensional scanning for three-dimensional imaging. The ultrasonic apparatus includes a transducer, installed within a catheter, which transmits ultrasonic waves in a direction corresponding to a transducer drive signal frequency and receives reflection waves from an examination subject, to display a tomogram image obtained by the transducer. Also, the ultrasonic apparatus includes an ultrasonic probe having arrayed transducers in an elongated shape which transmit ultrasonic waves in a direction corresponding to a transducer drive signal frequency and receive reflection waves from an examination subject, and a device for electronic scanning and focusing in a direction of array of the transducers in the elongated shape, and electronic scanning in a direction perpendicular to that direction is conducted by changing the transducer drive signal frequency.
