Abstract: A dual- or multi-resonant RF/MR transmit and/or receive antenna (1, 2) especially in the form of a planar antenna or a volume array antenna (also called antenna array) is used for MR image generation of at least two different nuclei like e.g. 1H, 19F, 3He, 13C, 23Na or other nuclei having different Larmor frequencies. The antenna is coupled by an inductive coupling device (LI) with related transmit/receive channels (T/R). By such an inductive coupling, the tuning and matching of the antenna at the different resonant frequencies is easier than in case of a galvanic connection. The dual- or multi-resonant RF/MR transmit and/or receive antenna is used in an MR imaging apparatus.

Abstract: A magnetic resonance imaging device produces a magnetic field gradient with parallel driving of positive-side subcoils and negative-side subcoils with different power sources in the magnetic field gradient direction, to detect a misalignment in drive timing of the positive side and the negative side. Pulse sequences for timing misalignment detection having a slice magnetic field gradient pulse and a read-out magnetic field gradient pulse in the same direction as a magnetic field gradient of interest are executed. A positive-side slice echo and a negative-side slice echo of the magnetic field gradient are acquired. A phase difference between a positive-side projection image and a negative-side projection image is derived by computation with phase error from other factors being removed. From the slope of the phase difference with respect to a location, the drive timing misalignment between the positive-side subcoil and the negative-side subcoil of the magnetic field gradient production is detected.
