PROBLEM TO BE SOLVED: To enable to check a relation between the position of an object position in a patient's body and the position of a puncture probe and the position of the puncture probe outside the body by synthesizing a plurality of video information obtained by driving an ultrasonic sensor and data relating to the puncturing depth of a puncture probe and the axis deviation angle. SOLUTION: A plurality of B mode images are obtained by an ultrasonic sensor 12 built in a probe guide 13 and inputted as video signals 17 into an image composing part 21 for monitor. On the other hand, data of the puncture depth of a puncture probe 11 by a marker 18 and data of the axis deviation angle of sector scanning of the builtin ultrasonic sensor with by a marker 19 are inputted as outer information 16 into the image composing part 21 for monitor through a CCD camera 15. At the image composing part 21, the three- dimensional relation between an object position 10a in a body and the puncture probe 11 is calculated, and the relation between positions of the object position 10a in a body and the puncture probe 11 is displayed on the display part of a three-dimensional monitor, and the outer position state is displayed on the display part 22 for a position confirmation monitor 22. |
