DEVICE BEING INTRODUCED INTO SUBJECT BODY |
摘要 |
A body-insertable apparatus includes a permanent magnet (22) covered by a biocompatible material (23), e.g., ceramic, inside a capsule-like shell (21). At the same time, a space between the shell (21) and the permanent magnet (22) is filled with a filling material (24) made of a material, such as barium sulfate, that does not adversely affect the subject body (1). An intensity of a constant magnetic field that is generated from the permanent magnet (22) and is output from the body-insertable apparatus inside the subject body (1) is detected outside the subject body (1). Thus, the simply-structured body-insertable apparatus allows for a safe acquisition of positional information thereof without a negative influence on the subject body even when the shell is decomposed. |
