DEVEOPMENT OF AN IMPROVED TREATMENT CHAIR FOR RADIATION THERAPY

本项目旨在设计一种治疗椅， 克服了商业上的固有设计限制， 可用的椅子 这把椅子将独立于 治疗床，以便允许在任何情况下进行相反的场治疗 以扩展的等中心方式定向（ 旋转的距离将大于标准等中心点 加速器）。 这把椅子将能够准确， 在横向、纵向和纵向上的可再现旋转和平移 和垂直平面。 如果可能的话，椅子会正常工作 使用标准放射治疗模拟器， 定位、固定和治疗计划。 椅子将根据“工具保持器”原则进行设计。 也就是说， 主席将作为一个平台，提供 各种附加装置的附件， 这样的方式，使他们允许适当的固定 患者，不限制治疗。

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). This chair will be capable of accurate, reproducible rotation and translation in the lateral, longitudinal and vertical planes. If possible, the chair will function properly with a standard radiotherapy simulator to permit proper localization, immobilization and treatment planning. The chair will be designed on the "tool holder" principal. That is, the chair will function as a platform, providing for the attachment of various additional devices which can be placed in such a manner so that they allow proper immobilization of the patient without restricting treatment delivery.
