Producers time-variable magnetic fields of a magnetic resonance apparatus and magnetic resonance apparatus with the producers

摘要

Producers time-variable magnetic fields of a magnetic resonance apparatus, the an examination room to be examined for receiving at least one region of an examination subject, comprising the following features:– The conductors of a gradient coil system of the originator define a the examination space at least partially surrounding region (121, 122, 123, 124, 125, 131, 132, 221, 222, 223, 224, 225, 231, 232, 321, 322, 323, 324, 325, 331, 332, 421, 422, 423, 424, 431, 432, 433, 434),– the region (121, 122, 123, 124, 125, 131, 132, 221, 222, 223, 224, 225, 231, 232, 321, 322, 323, 324, 325, 331, 332, 421, 422, 423, 424, 431, 432, 433, 434) contains at least a partial area (131, 231, 331, 431, 433), the free of conductors of the gradient coil system, and the conductor (151, 152, 251, 252, 351, 352, 451) includes a radio frequency antenna of the originator, and– a field return flow space (132, 232, 332, 432, 434) for fields of the radio frequency antenna extends, starting from..
