RADIATION FIELD MODELING AND COMPUTERIZED TREATMENT PLANNING

这是正在进行的研究和开发。计算能力 光子束和电子束产生的吸收剂量分布 最普遍的特征是放射治疗的基础。的 辐射场模型之前已经描述过。它以 沿沿着三条相互垂直的参考线的经验分布 在“主字段”中。“ 也这种方法的一个优点是， 数据，因此可以很容易地实现。 在Macintosh II上实施我们的治疗计划 系统仍在继续。该系统的特点需要一个 完全不同的方法，以纯粹的计算部分，该项目 光子束即将完成，但“工具箱”将直接 适用于其他应用，包括单克隆抗体剂量测定 和成像。

This is ongoing research and development. The capability to calculate the distribution of absorbed dose produced by photon beams and electron beams to the most general characteristics is fundamental to radiotherapy. The radiation field model has been described before. It takes as a basis the empirical distributions along three mutually perpendicular reference lines in a "master field." This concept is applied to the beam-modifying devices as well. One virtue of this approach is that it requires few experimental data and thus can be implemented very easily. The implementation of our treatment planning programs on a Macintosh II system is continuing. The characteristics of this system require a drastically different approach as to the pure calculation part The project is nearing completion for photon beams, but the "toolbox" will be directly applicable to other applications, including monoclonal antibodies dosimetry and imaging.
