  • Publication number: 20070265496
    Abstract: An object of the present invention is that the examiner easily picks up a series of images over a desired region in a desired digestive tract without such troublesome examination work that the examiner successively knows the imaging field to the inside of the digestive tract. A body-insertable device system of the invention includes a capsule endoscope 1, a permanent magnet 3, and a position display sheet 2. In the capsule endoscope 1, a imaging unit for picking up the images of the insides of an subject 100, and a magnet are contained in a casing. The capsule endoscope sends a radio signal containing information of the images of the insides of the subject 100 to outside the capsule endoscope. The permanent magnet 3 generates a magnetic field for application to the capsule endoscope 1 in liquid Lq1 having been introduced into the subject 100 and changes at least one of a position and a posture of the capsule endoscope 1 by the magnetic field.
