PROBLEM TO BE SOLVED: To prevent occurrence of magnetic attraction more surely than before.SOLUTION: A magnetic field attraction prevention device according to one embodiment includes: a detection module which includes a detection magnetic field generation part for generating a magnetic field for approach detection, a magnetic field detection part for detecting the strength of the magnetic field for the approach detection generated by the detection magnetic field generation part, and a determination part for determining presence/absence of the approach of a magnetic body to a magnetic resonance diagnostic apparatus on the basis of the strength variation of the magnetic field for the approach detection detected by the magnetic field detection part, and detects the approach of the magnetic body to the magnetic resonance diagnostic apparatus through a first gateway provided between a photographing chamber where the magnetic resonance diagnostic apparatus is installed and an anterior chamber adjacent to the photographing chamber; a prevention part for preventing the magnetic field attraction of the magnetic body by the magnetic resonance diagnostic apparatus according to the detection of the approach of the magnetic body by the detection module; and a control part for controlling the detection module so as to start a detecting operation in response to the operation of a door provided on a second gateway provided in the anterior chamber differently from the first gateway. |
