Patent ID: 8362775

Claim:
A magnetic resonance system configured for generating a magnetic resonance exposure of an examination subject, said system comprising: a magnetic resonance scanner having an examination tunnel therein configured to receive an examination subject therein; a whole-body antenna built into said scanner housing, said whole-body antenna comprising: two connection terminals and said whole-body antenna cylindrically extending around said tunnel along a longitudinal axis of said tunnel and said whole-body antenna; a radio-frequency supply device that supplies radio-frequency signals to said whole-body antenna that cause said whole-body antenna to emit a radio-frequency field in said tunnel, said radio-frequency supply device comprising: a radio-frequency generator that generates said radio-frequency signal, a signal splitter that divides said radio-frequency signal from said radio-frequency generator into two partial signals that are phase-shifted by 90° relative to each other, and two radio-frequency feed lines respectively connected with said two connection terminals of said whole-body antenna in order to respectively feed said two partial signals to said whole-body antenna; and said whole-body antenna having an intrinsic transmission characteristic that causes the radio-frequency field to be elliptically polarized in plane that is perpendicular to said longitudinal axis to and have a major ellipse axis that is tilted by a non-zero angle relative to the horizontal, at least in an unloaded state of said examination tunnel with no examination subject present therein.
