PROBLEM TO BE SOLVED: To provide a biological magnetic field measuring instrument for obtaining a synthesized image of an image expressing biological function information and a pattern image. SOLUTION: Marks expressing the (xz) and (yz) surface of a coordinate system are provided on the peripheral face of a container of a SQUID fluximeter arranged in the (x) and (y) direction. A first laser spreading in the form of a fan within the (xz) surface, a second laser spreading in the form of a fan within the (yz) face and a third laser irradiating diagonally the surface of a bed in the form of a dot so that it mat cross the foregoing lasers are provided, the irradiation bearing of the second laser and the position of the bed in the (x) direction are adjusted so that the second laser may pass first and second markers arrange in the xiphoid process and jugular notch and irradiate the (yz) mark, the irradiation bearing of the first laser and the position of the bed in the (y) direction are adjusted so that the first laser may irradiate the (xz) mark and pass the first marker, and the bed is moved in the (z) direction so that the third laser may irradiate the first marker. The positioning of a subject for examination can be executed easily to obtain a synthetic image. |
