As for the radiotherapy system, the beam of radiation the dielectric material which the formation possible emission radiation source and, the magnetic resonance picture which at least includes one high frequency detection coil (MRI) is, with the emission radiation source and the high frequency detection coil in order and at least to cover one high frequency detection coil from the beam of the device and radiation is grounded electrically and, it includes. In addition, in order to be grounded electrically, part was covered at least by the dielectric material which conforms, the magnetic resonance picture (MRI) the high frequency detection coil for the device is disclosed.放射線治療システムは、放射線のビームを生成可能な放射線源と、少なくとも一つの高周波検出コイルを含む磁気共鳴画像(MRI)装置と、放射線のビームから少なくとも一つの高周波検出コイルを遮蔽するための、放射線源と高周波検出コイルとの間にある電気的に接地された誘電材料と、を含む。また、電気的に接地されるように適合された誘電材料によって少なくとも一部が覆われた、磁気共鳴画像(MRI)装置のための高周波検出コイルが開示されている。
