摘要： A patient support system comprises a base, an upstanding support, and a couch attached to the support and having a cantilever section extendable beyond the support; the support including a couch drive means to adjust the position of the couch relative to the support; further comprising a support drive means for translationally driving the support relative to the base in the direction of the cantilever section. This removes inaccuracies from patient position measurements that result from changes in the cantilever geometry during movement of the patient from a measuring position to a treatment position. The support drive means can be located in the base or in the support, and allows the patient support system as a whole to be translated, thereby permitting the patient to be moved into and out of an enclosed treatment area without affecting the vertical location of the patient. The only change to the patient position is in the translational position, which can be calibrated by way of fixed end stops for the support drive means. The present invention further relates to a radiotherapy apparatus, comprising a patient support as set out above, and an enclosed treatment area positioned in line with the cantilever section.

摘要翻译： 患者支撑系统包括底座，直立支撑件和连接到支撑件的沙发，并且具有可延伸超过支撑件的悬臂部分; 包括沙发驱动装置的支撑装置用于调节沙发相对于支撑件的位置; 还包括支撑驱动装置，用于在所述悬臂部分的方向上相对于所述基座平移地驱动所述支撑件。 这消除了患者从测量位置移动到治疗位置的过程中由于悬臂几何形状的变化引起的患者位置测量的不准确性。 支撑驱动装置可以位于基座或支撑件中，并且允许患者支撑系统作为整体被平移，从而允许患者被移入和移出封闭的治疗区域，而不会影响患者的垂直位置 患者。 患者位置的唯一变化是在平移位置，其可以通过用于支撑驱动装置的固定端部止动器进行校准。 本发明还涉及一种放射治疗装置，其包括如上所述的患者支架和与悬臂部分成一直排列的封闭治疗区域。
