<P>PROBLEM TO BE SOLVED: To provide a subject interior position detecting system precisely detecting the position of a subject interior introduction device despite the presence of the organ. <P>SOLUTION: This subject interior position detecting system is provided with a test capsule 2 incorporating a permanent magnet and a position detector 3 detecting the position of the test capsule 2 based on the strength of a constant magnetic field generated by the permanent magnet incorporated in the test capsule 2. The position detector 3 is provided with magnetic field strength detectors 6a-6h, fixing members 7a and 7b fixing the magnetic field strength detectors 6a-6h to the subject 1, and a position information lead-out device 8 leading out a distance between the test capsule 2 and the magnetic field strength detectors 6a-6h based on the magnetic field strength detected by the magnetic field strength detectors 6a-6h and leading out the position of the test capsule 2 based on the led-out distance. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
