Patent ID: 7898255

Claim:
An inspection apparatus using magnetic resonance, comprising, a unit for generating a static magnetic field in a vertical direction, a unit for generating an excitation RF pulse that is applied to a test object placed in the static magnetic field, a unit for generating a magnetic field gradient that is superimposed on the static magnetic field, a receiver coil that is made up of multiple sub-coils and that detects a nuclear magnetic resonance signal generated from the subject, the multiple sub-coils further comprising, a first coil that is placed in a plane including an axis parallel to a direction of the static magnetic field, and produces a current loop around an outer circumference of the test object, a second coil that produces even-numbered current loops in a plane intersecting the plane of the current loop of the first coil, and a third coil that produces odd-numbered current loops in a plane approximately parallel to the plane of the current loops of the second coil, wherein, the second coil and the third coil are arranged in such a manner that an array direction of the current loops produced by the second coil is equal to the array direction of the current loops produced by the third coil, and in the array direction of the current loops, a position where a sensitivity of the second coil is minimized approximately coincides with a position where the sensitivity of the third coil is maximized.
