Abstract

The medical device guidance system include a magnetic guidance device which generates a guidance field in an arbitrary direction to guide a capsular medical device and carry out movement and posture control, a position detection device which detects the present position by a magnetic field generated by the capsular medical device and a position calculating and correcting section which forms an estimation equation of an undesired magnetic field generated from a guidance coil and subtracts an estimation equation result from the detection result of the magnetic field detecting section, according to the present position of the capsular medical device that controls the position and posture by a guidance field relative to the position detection device, and corrects the present position by excluding a desired magnetic field generated from a guidance coil.
