ABSTRACT:
A magnetic resonance apparatus comprises a main probe coil adapted for transmission and reception of a high frequency to and from a large region of an object under examination or for transmission of the high frequency to the object, a local probe coil formed of a surface coil adapted for transmission and reception of a high frequency to and from a local region corresponding to a local portion of the object or for reception of the high frequency, and a main gradient coil adapted for application of a gradient magnetic field to a large region of the object. The local probe coil is used for measurement of the local region. The magnetic resonance apparatus is further provided with a relatively small-sized local gradient coil for producing a local gradient magnetic field in the sensitive region of the local probe coil and its vicinities only.
