In minimally invasive intravascular interventions with the aid of catheters, it is necessary to incorporate a detecting system of the probe during all the time of operation. To this end, the standard X-ray imaging is used in the most cases. However, a high radiation dose caused by X-ray is an important health risk for clinicians and patients. In order to reduce the radiation dose, new navigation systems that replace or reduce the use of X-ray imaging must be developed. We have developed a system composed of Magneto-Impedance(MI) sensors outside the patient, and a magnet on the tip of the catheter. It is considered that the effect of the magnetic field on the human body is low. But our system is not still enough to use for the practical interventions because of the narrowness of detecting area and the noises. In this study, we proposed movable sensor system and simulated it.
