System for detecting travel state of capsule endoscope in subject
First Claim
1. A system comprising:
- a device that is swallowed, passes through a subject, and includes a magnetic field generator generating a constant magnetic field; and
a travel state detector that includes a magnetic detector, disposed in a fixed relative position to the subject, detecting an intensity of a constant magnetic field output from the magnetic field generator, a position processor calculating a position of the device in the subject based on the intensity of the magnetic field detected by the magnetic detector, and a travel state processor determining a travel state of the device in the subject based on the position calculated by the position processor.

Abstract
A system includes a device that is swallowed, passes through a subject, and includes a magnetic field generator generating a constant magnetic field; and a travel state detector. The travel state detector includes a magnetic detector, disposed in a fixed relative position to the subject, detecting an intensity of a constant magnetic field output from the magnetic field generator. The travel state detector also includes a position processor calculating a position of the device in the subject based on the intensity of the magnetic field detected by the magnetic detector, and a travel state processor determining a travel state of the device in the subject based on the position calculated by the position processor.
