Abstract:
1. A capsule medical device guidance system comprising: a capsule medical device that includes an imaging unit that captures an image in a subject, a transmitting unit that transmits an image captured by the imaging unit to the outside, and a magnetic field response unit; a magnetic field generator that generates a magnetic field to the magnetic field response unit to guide the capsule medical device; an operation input unit for inputting operation information for magnetically guiding the capsule medical device; a control unit that controls the magnetic field generator to guide the capsule medical device in accordance with the operation information input by the operation input unit; and a storage unit that stores control content by the control unit, wherein the magnetic field generator selectively generates, in a space in which the capsule medical device is guided, either: when the control unit switches the magnetic field generated by the magnetic field generator from the trapping magnetic field to the gradient magnetic field, the control unit causes the storage unit to store a generation position on the horizontal plane of the trapping magnetic field, and when the control unit switches a magnetic field generated by the magnetic field generator from the gradient magnetic field to the trapping magnetic field, the control unit causes the magnetic field generator to generate the trapping magnetic field at the position stored in the storage unit.
