ABSTRACT:
An ultrasonic diagnostic apparatus includes plural ultrasonic transducers, a catheter signal detection unit and a position detection unit. The plural ultrasonic transducers are arrayed two-dimensionally for transmitting and receiving ultrasonic waves to and from an object. The catheter signal detection unit is configured to acquire a reception signal of a frequency modulated continuous wave from reception signals from at least three of the plural ultrasonic transducers. The frequency modulated continuous wave is transmitted from a catheter inserted in the object. The position detection unit is configured to detect a position of the catheter based on the acquired reception signal of the frequency modulated continuous wave.
