Abstract: In a method for guiding brachytherapy radiation treatment the patient is supported on a table and an MR magnet is brought into the treatment bunker through doors for imaging while the after-loader for the radiation source delivery is stored away in a storage location outside the RF shield. A safety system controls movement of the after-loader and the magnet. Images of the patient obtained while the patient is on the table are used to locate the applicator with respect to the lesion and organs-at-risk. The MR and X-ray compatible patient support table with MR coil integration includes a removable end-extension, which provides pelvic access for applicator insertion.

Abstract: Apparatus for radiation therapy combines a patient table, an MRI and a radiation treatment apparatus mounted in a common treatment room with the MR magnet movable through a radiation shielded door to an imaging position. An initial MR image and an initial X-ray image is used to generate an RT program for the patient to be carried out in a plurality of separate treatment steps. Before carrying out the procedure, a registration step is performed using a phantom by which X-ray images are registered relative to MR images to generate a transformation algorithm required to align the MR images of the part of the patient relative to the X-ray images. Prior to each separate treatment step a current MR image of the part of the patient is obtained and the transformation algorithm data is used from the current MR image is used in guiding the RT treatment step.
Abstract translation: 用于放射治疗的装置将安装在公共治疗室中的患者台，MRI和放射治疗装置与可通过辐射屏蔽门移动到成像位置的MR磁体组合。 使用初始MR图像和初始X射线图像来生成用于在多个单独的处理步骤中执行的患者的RT程序。 在执行该过程之前，使用相对于MR图像登记X射线图像的体模执行登记步骤，以产生将患者部分的MR图像相对于X射线图像对准所需的变换算法 。 在每个单独的处理步骤之前，获得患者部分的当前MR图像，并且使用来自当前MR图像的变换算法数据来指导RT治疗步骤。
