New coil geometries obtained by computer simulations from the crossed-ellipse rf coil are reported. These geometries with elliptical transverse section improve the signal-to-noise ratio with respect to the classic ellipse and saddle coils. The increase of signal-to-noise ratio is mainly due to the reduction of coil losses and to the better B1 efficiency and distribution.

Abstract
New coil geometries obtained by computer simulations from the crossed-ellipse rf coil are reported. These geometries with elliptical transverse section improve the signal-to-noise ratio with respect to the classic ellipse and saddle coils. The increase of signal-to-noise ratio is mainly due to the reduction of coil losses and to the better B1 efficiency and distribution.File in questo prodotto:
