Producers time-variable magnetic fields for a magnetic resonance apparatus and magnetic resonance apparatus with such a generator time-variable magnetic fields

摘要

Producers (13a,...) time-variable magnetic fields (43, 51, 53, b1) having a primary gradient coil unit (15) for generating a gradient magnetic field in an examination zone (9, 9a) of a magnetic resonance apparatus (1), wherein the primary gradient coil unit (15) for receiving at least of a gradient coils conductor (35a, .. 35C, 39a, .. 39C), a central region (14a), an outer region (14b) and at least one connecting the two regions of the connecting region (14c, .. 14F), wherein the outer region (14b) surrounds the central area (14a) and wherein between the central area (14a) and the outer region (14b) at least one intermediate space (16a, .. 16D) is arranged, which is free from the gradient coils conductor (35a, .. 35C, 39a, .. 39C) of the primary gradient coil unit (15), and in which a high frequency antenna element (21a,...) is arranged.
