A magnetic resonance antenna includes a surface coil and a receive coil. The magnetic resonance antenna includes one or more antenna elements. The magnetic resonance antenna further includes a preamplifier for the antenna element and a coil former for supporting the antenna element. The coil former is formed from a porous material. The antenna is divided into an irradiation zone and at least one reduced radiation zone. The preamplifier for each of multiple antenna elements is located within the at least one reduced radiation zone. The multiple antenna elements are located at least partially within the irradiation zone. The coil former has a perimeter. The irradiation zone extends continuously from a first edge of the perimeter to a second edge of the perimeter. The first edge and the second edge are opposing edges.

Magnetic resonance imaging receive coil with reduced radiation attenuation

The present disclosure relates to a therapy system () comprising a radiotherapy device () configured to deliver and direct a radiotherapy beam along an axis to a predefined target position () in an imagine zone () within an MR module () of the therapy system (). The predefined target position () is matched with a position of an RF coil () of the MR module ().

Therapy system containing an MRI module and means for determining the position of an RF coil

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.
