目标是进行必要的研究，以开发一种计算机化的 用于癌症治疗直线加速器的多叶准直器。 具体 目标如下： 1.开发可靠、准确的机械系统， 治疗入口的成形。 2.开发机电一体化的位置控制装置 准直器以快速和精确的方式离开。 3.开发一个强大的软件包，不仅控制和 监控系统，而且使用方便。 4.设计和制造一个功能齐全的现场原型， 用幻影测试 5.与马萨诸塞州总医院的放射部合作 医院应确保所提议的准直器适用于 临床放射治疗

The goal is to conduct the research necessary to develop a computerized multi-leaf collimator for use with cancer therapy linacs. The specific objectives are as follows: 1. To develop the mechanical system required for dependable and accurate shaping of the treatment portal. 2. To develop the electromechanical apparatus to control the position of the collimator leaves in a rapid and precise manner. 3. To develop a powerful software package which not only controls and monitors the system, but which also is convenient to use. 4. To design and fabricate a fully functional, field prototype for thorough testing with phantoms. 5. To collaborate with the Department of Radiation at Massachusetts General Hospital to insure that the proposed collimator will be practical for clinical radiation therapy.
