PROBLEM TO BE SOLVED: To prevent a leaked magnetic field from affecting a subject or operation apparatus or the like when being used for an operation, to ensure a sufficient working space without moving the subject during the operation and to enable to use normal apparatus having a high versatility as they are as the apparatus or the like which are used for the operation. SOLUTION: A magnetic flux suppressing means which suppresses a magnetic flux leaking from a magnetic field-generating means is provided so that a magnetic field generated from the magnetic field-generating means may not affect the subject and the vicinity when the picking up of a tomographic image is not performed. Since the magnetic flux leaking out from the magnetic field- generating means is suppressed by the magnetic flux suppressing means, unfavorable effects of the leaked magnetic field to the operation environment can be suppressed.
