Abstract: There is a method for measuring a deviation amount of a measuring device, comprising: transferring, by using a transfer device, the measuring device to a position in an area specified by transfer position data; acquiring measurement values using four or more sensor electrodes of the measuring device; identifying two or more sensor electrodes among the four or more sensor electrodes, the two or more sensor electrodes outputting, as the measurement values, capacitances that satisfy a reliability standard; and calculating the deviation amount based on the measurement values of the identified two or more sensor electrodes.

Abstract: The measurement apparatus and the MRI apparatus are provided with a magnet, which forms a specified static magnetic field, and a magnetic field gradient coil for applying a gradient magnetic field on the static magnetic field, and the magnetic field gradient coil is a structure that is separated from the magnet and is configured to be movable relative to the magnet. The MRI apparatus is characterized in that MRI images of a subject are acquired while the magnetic field gradient coil is moving relative to the magnet.
