An ultrasonic diagnostic apparatus 12 outputs echo data to a host controller 20. In the host controller 20, a tissue coordinate operation unit 48 computes coordinate information of a tumor 30 using a three dimensional probe 10 as an origin; a probe coordinate operation unit 52 computes coordinate information of the three dimensional probe 10 using, as its origin, an X-ray source apparatus 18 which functions as a reference position; and a combined tissue coordinate operation unit 54 uses the coordinate information of the tumor using the three dimensional probe 10 as its origin and the coordinate information of the three dimensional probe 10 using the X-ray source apparatus 18 as its origin to compute coordinate information of the tumor 30 using the X-ray source apparatus as its origin, and outputs the computed coordinate information to the X-ray source apparatus 18.
