DEVELOPMENT OF AN IMPROVED TREATMENT CHAIR FOR RADIATION THERAPY

本项目旨在设计一种治疗椅，它克服了 市面上可买到的椅子固有的设计局限性。这把椅子 独立于治疗床而起作用，从而允许相反的 以扩展等心方式在任何方向上进行的场处理( 旋转中心的距离将大于标准距离 加速器的等中心)。它将能够准确地、可重复性地 在横向、纵向和垂直平面上的旋转和平移。 如果可能，座椅将与标准的放射治疗模拟器一起工作 以允许适当的定位、固定和治疗计划。 这把椅子是按照“工具平台”的原则设计的。也就是说， 椅子将起到平台的作用，允许连接各种 可以以它们允许的方式放置的附加设备 在不过度限制治疗的情况下适当地固定病人 送货。

This project is intended to design a treatment chair which overcomes the inherent design limitations of commercially available chairs. This chair win 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.
