Vivo observation and methods vivo observation system

摘要

An object of the present invention can be imaged reliably vivo images continuous image portion are overlapped at least partially in the body between the images. Vivo observation system 1 according to the present invention, a magnetic field generating unit 3 and the capsule endoscope 2 is introduced into the body of a subject to generate an external magnetic field to the two lens capsule endoscope in the subject, I and a control unit 11 for controlling the magnetic field generating unit 3. The capsule endoscope 2 includes an illumination unit for illuminating illumination light by the body of the subject, and an imaging unit that captures vivo images of the subject illuminated by the illuminating unit. And alter the magnetic field direction of the external magnetic field to the magnetic field generating unit 3 at an angular velocity is multiplied value is less than the angle of view and the frame rate of the imaging unit, the control unit 11, the capsule endoscope 2 to follow the magnetic field direction I alter the magnetic field generating unit 3 in the angular velocity of the imaging direction.
