摘要： The accurate position detection without being affected by an unnecessary second magnetic field can be realized by calculating the unnecessary second magnetic field induced and generated at positions of magnetic field sensors by a guiding coil arranged around the position detection area of the medical device due to an action of a first magnetic field generated by a magnetic field generator, at the time of position detection, and the second magnetic field is subtracted from the first magnetic field detected by the magnetic field sensors to calculate corrected magnetic-field information. Further, LUTs that store beforehand numerical information having a correlation with the second magnetic field induced and generated at the positions of magnetic field sensors are used to calculate the second magnetic field, thereby enabling to reduce an amount of calculation performed each time and realize high speed processing.

摘要： A system includes a capsule body having a casing introduced into a subject to perform, in liquid, examination of or treatment on the interior of the subject, the casing containing a permanent magnet, a mass of the casing excluding the magnet being set to be less than a product of a volume of the casing and a density of the liquid; a magnetic field generator that generates a magnetic attraction for the magnet to guide the capsule body; and a magnetic field generation device that controls the magnetic field generator to generate the magnetic attraction by setting a maximum value of the generated magnetic attraction vertically upward to the capsule body, to be equal to a maximum value of the generated magnetic attraction vertically downward to the capsule body, and by setting the maximum values to be less than a value obtained by multiplying a mass of the magnet by a gravitational acceleration.
