US 2008/0306358 A1 · Body Insertable System, Receiving Apparatus, and Body Insertable Apparatus

Abstract

A receiving apparatus 3 which is an element of a body insertable system is configured with a reciving unit 6 including receiving antennas 8a to 8d and a reception processing device 9, and a postion detecting unit 7 including transmitting antennas 10a to 10d, a first linear magnetic field generator 11a, a second linear magnetic field generator 11b, a diffusr magnetic field generator 12, and a processing device 13, and the receiving unit 6 and the postion detecting unit 7 are formed seperately and independently of each other. Therefore, when the body insertable system is used for acquisition of intra-subject information which is acquired by the capsule endoscope 2 and position detection of the capsule endoscope 2, both the receiving unit 6 and the position detecting unit 7 are used, whereas when the body insertable system is used only for the acquisition of the intra-subject information, it is possible to use only the receiving unit 6, whereby a burden on the subject at a time of use is restricted to a minimum degree according to the purpose of use while increase in operational cost is suppressed.

the body insertable apparatus includes:
an intra-subject information acquiring unit that acquires the intra-subject information;
a magnetic field sensor that detects a magnetic field in a region where the body insertable apparatus is located;
and
a radio transmitting unit that transmits radio signals including at least the intra-subject information, and
the receiving apparatus includes:
a receiving unit that includes at least a receiving antenna which receives the radio signals transmitted by the body insertable apparatus and a receiving circuit which performs reception processing on the radio signals received by the receiving antenna;
and
a position detecting unit that includes a magnetic field generator which generates a predetermined magnetic field for position detection in a region where the body insertable apparatus can be present, and a position calculator that calculates a position of the body insertable apparatus based on a result of detection of the magnetic field for position detection acquired by the magnetic field sensor, the position detecting unit being formed separately and independently of the receiving unit.
