Intra-subject position display system
First Claim
1. An intra-subject position display system for displaying a position of an intra-subject device, which is introduced into a subject and moves therein, the intra-subject position display system comprising:
- a plurality of outer surface sensors configured for arrangement on an outer surface of the subject;
an outer surface information deriving section for deriving outer surface information including information on the shape of the outer surface of the subject based on positions of the outer surface sensors determined from a signal associated with each of the plurality of outer surface sensors;
a position detector for detecting a position of the intra-subject device; and
a relative position information deriving section for deriving relative position information of the intra-subject device to the outer surface of the subject; and
a display device for displaying the position of the intra-subject device relative to the outer surface of the subject based on a result of the detection made by the position detector.

Abstract
An intra-subject position display system for displaying a position of an intra-subject device, which is introduced into a subject and moves therein, wherein a relative position of the intra-subject device to an outer surface of the subject is detected and displayed. The position of the intra-subject device is displayed in a relation with the outer surface of the subject. Thereby, it is possible to easily determine in which site of the subject the intra-subject device exists. The present invention is effective to recognize a position of, for example, a capsule type endoscope or a test capsule therefor in the subject (e.g., a human body). To recognize the outer surface of the subject, for example, a plurality of radio devices are arranged on the outer surface of the subject and their radio signals are analyzed.
