摘要：
A magnetic resonance transmit and/or receive antenna system configured for being used in combination with a magnetic resonance radiotherapy system. The antenna system can include at least one antenna for transmitting and/or receiving radio frequency signals and a cover enclosing the antenna components. The antenna can include antenna components and the cover can include a spatially varying thickness and/or density towards an outer edge of the surface and/or next to an antenna component as to make the change in radiation attenuation between the enclosing cover compared to the antenna component and/or air more gradual.
