The purpose of this study is to develop a support software to place ultrasound transducer, which produces local acoustic radiation force, for active induction of a micro object, representing a thin catheter, through blood vessel network. First, based on the image analysis of 3D blood vessel network, which was obtained using echography, the system calculates the possible area of the ultrasound transducer to be able to induce a micro object to desired path in blood vessel network. Meanwhile, due to the shape of body surface and the position of the ribs, which was obtained by an optical position sensor, the common area with the body surface was derived. Then, considering the position and the movable area of the robot, which grasps and moves the ultrasound transducer, the system indicates the candidate commands for the robot. To verify the system performance, we have conducted a simulation for active induction experiment of thin catheter through blood vessel network of a normal volunteer subject. As the result, we confirmed the variation of the thin catheter induction according to both body posture and breathing condition.
