DEVEOPMENT OF AN IMPROVED TREATMENT CHAIR FOR RADIATION THERAPY

本项目旨在设计一种治疗椅， 克服了商业上可获得的 椅子 这张椅子将独立于治疗 治疗床，以允许在任何方向上进行对射野治疗 以扩展的等中心方式（旋转中心将 在大于标准等中心点的距离处， 加速剂）。 它将能够准确，可重复 横向、纵向和垂直方向的旋转和平移 飞机。 如果可能的话，椅子将按照标准运行。 放射治疗模拟器以允许适当的定位， 固定和治疗计划。 椅子是根据“工具平台”原则设计的。 的 椅子可以作为一个平台， 各种附加设备，可以放置在这样的方式， 它们允许患者适当固定， 不适当地限制了治疗的实施。

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.
