Abstract: A capsule medical system is provided that accurately detects the location at which biological information, such as an image captured in a living body, is acquired. A circular loop antenna 23 incorporated in an endoscopic capsule traveling in a living body transmits a high-frequency signal and a plurality of antennas 11a to 11i disposed on a body surface of the living body receives the signal. A CPU 36 defines the initial location and orientation of the antenna 23. The CPU then performs an estimation process on the initial location and orientation so as to compute new estimated location and orientation and update the initial location and orientation to the new location and orientation. The CPU similarly performs the estimation process on the updated location and orientation. The CPU performs accurate location estimation by repeatedly performing the estimation process until the amount of shift of the location computed and updated by the estimation process reaches a sufficiently small value.

Abstract: Insertion of a probe comprising an array of 16 source coils through a forceps channel of an electronic endoscope prepares the source coils in the insert of electronic endoscope for use in monitoring work objects. To a bed where a patient lies, are mounted two sets of sensor coils crossing at a right angle to each other, each of which comprises at least four single core coils with a common central axis placed on the same line in the same direction. A control section of the system gives signals with radiofrequencies (driving signals) through source cables to the source coils, to excite the source coils to generate magnetic fields around them.
