Abstract
A generator of time-variable magnetic fields of a magnetic resonance apparatus, said apparatus having an examination space for imaging of at least one area of an examination subject to be examined, incorporates the following features: the conductors of a gradient coil arrangement of the generator extent over an essentially disk-shaped area, the area includes at least one sub-area which is free from conductors of the gradient coil arrangement and within which are arranged conductors of a high-frequency antenna of the generator, and a field backflow space, which is available inter alia for fields of the high-frequency antenna, extends away from the examination space, starting from the sub-area.
Claims16
A magnetic resonance device, comprising:
- an examination space for accommodating at least a portion of a subject to be examined;
- and
- a generator for generating time-variable magnetic fields, the generator comprising:
- a gradient coil arrangement having a plurality of first conductors extending within a first area formed as a plate, the first area having a first sub-area free of the first conductors;
- a second area within which a magnetic field backflow occurs, the second area extending from the first sub-area in a direction away from the examination space;
- and
- a plurality of second conductors arranged within the first sub-area operatively connected to a high-frequency antenna of the generator.
