Abstract: The saddle coil is used in MRI/MRS (magnetoresonance imagging/scanning) applications in the position of gradient coils or RF probes. Gradient coils produce a linearly growing magnetic field along one axis and a homogenous magnetic field in the remaining ones, which gives us something like a coordinate system used for evaluating the measured data. RF Saddle coils should have a constant magnetic field in its entire area and serve as both the transmitter and the receiver for experiments. Those coils are tuned to the specified frequencies and obtain spectral ranges we want to process. The major emphasis is put on the good matching of the coil to the system instead on achieving a good homogenity of the magnetic field. Also a high Q factor of the coil is preferred. The methods of the RF Saddle coil design are based on thr inductance calculation and evaluation of the incident resonant frequency. In this article a method of Saddle coil design for large objects is described, resonant frequency calculations are proposed and in the conclusion the two coils are compared.
