A small computer has been interfaced to a linear accelerator used for routine radiotherapy. The objectives are to assess the rate and magnitude of some of the mistakes which may occur, to prevent these where possible and to assist radiographers with record keeping. In this paper we describe our approach to the problem, the apparatus used, the computer program, and the results of several years of operating experience while the system was continually being developed. On one linear accelerator, we estimate that an error has been prevented roughly once in every 500 field parameters set. The most common error is in setting the diaphragms and a detailed analysis is given of possible reasons. Doses in monitor units are recorded automatically and a running total of cumulative dose is maintained; plans for the printing of the dose in rads at selected points are discussed.
一台小型计算机已与用于常规放射治疗的直线加速器相连接。目的是评估可能出现的一些错误的发生率和严重程度，尽可能预防这些错误，并协助放射技师进行记录保存。在本文中，我们描述了我们解决该问题的方法、所使用的设备、计算机程序以及在系统不断开发过程中数年的运行经验结果。在一台直线加速器上，我们估计每设置500个射野参数中大约就能预防一次错误。最常见的错误是设置准直器，文中给出了对可能原因的详细分析。监测单位的剂量会自动记录，并保持累积剂量的累计总数；还讨论了在选定位置打印拉德剂量的计划。
