DEVEOPMENT OF AN IMPROVED TREATMENT CHAIR FOR RADIATION THERAPY

本项目旨在设计一种治疗椅，它可以 克服了商用的固有设计限制 椅子。这把椅子的功能与治疗无关。 沙发，以允许在任何方向上进行相反的现场处理 以扩展的等中心方式(旋转中心将是 在大于标准等中心的 加速器)。它将能够准确地、可重复性地 横向、纵向和垂直方向的旋转和平移 飞机。如果可能的话，这把椅子将以标准的 放射治疗模拟器以允许适当的定位， 制动和治疗计划。 这把椅子是按照“工具平台”的原则设计的。那 是，椅子将起到平台的作用，允许连接 可以以这种方式放置的各种附加设备 他们允许适当地固定病人而不需要 不适当地限制治疗的提供。

This project is intended to design a treatment chair which overcomes the inherent design limitations of commercially available chairs. This chair will function independently of the treatment couch so as to permit opposed field treatment in any orientation in an extended isocentric fashion (the center of rotation will be at a distance greater than the standard isocenter of the accelerator). It will be capable of accurate, reproducible rotation and translation in the lateral, longitudinal and vertical planes. If possible, the chair will function with a standard radiotherapy simulator to permit proper localization, immobilization and treatment planning. The chair is being designed on the "tool platform" principle. That is, the chair will function as a platform, allowing the attachment of various additional devices which can be placed in such a manner that they permit proper immobilization of the patient without unduly restricting treatment delivery.
