Title:
CAPSULE MEDICAL DEVICE GUIDANCE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/055578
Kind Code:
A1
Abstract:
A capsule medical device guidance system (301) stores, in a magnetic field condition storage unit (347), the position of generation on a horizontal plane of a peak magnetic field which constrains a capsule endoscope (10) in an arbitrarily defined position, when the magnetic field to be generated by a magnetic field generation unit (2) is switched from the peak magnetic field to a uniform gradient magnetic field which has an approximately uniform magnetic gradient and biases a permanent magnet of the capsule endoscope (10), and generates the peak magnetic field in the position stored in the magnetic field condition storage unit (347) when the magnetic field to be generated by the magnetic field generation unit (2) is switched from the uniform gradient magnetic field to the peak magnetic field.
