辛辛那提大学医学院放射治疗系与许多其他中心一样，使用计算机程序来协助比较拟议治疗计划的剂量分布。每次病人治疗的任何安排比一对平行的相对领域更复杂，试探性的想法是开发几个多领域的安排，并提交一个指定的格式到大学计算服务中心。如果在“眼球”评估之后，对所考虑的所有安排都不满意，则再次从那些提交给计算中心的安排中重复该过程，这一次产生可接受结果的可能性更大。随着数字计算机的巨大能力，人们很自然地问：“有没有可能消除这种'审判'程序？”这个问题的答案是肯定的。在解决问题的方法上，尽可能地消除了空间治疗计划中的人的直觉因素，并使其成为一种有效的方法。
The radiotherapy Department of the University of Cincinnati, College of Medicine, like many other centers, uses a computer program to assist in comparing dose distribution for proposed treatment plans. Each time a patient is treated with any arrangement more complicated than a pair of parallel opposing fields, tentative ideas are developed for several multifield arrangements and are submitted in a specified format to the University Computing Service Center. If after “eyeball” evaluation there is dissatisfaction with all the arrangements considered, again from those submitted to the computing center the process is repeated, this time with greater likelihood of producing an acceptable result. With the vast capability of digital computers available, one quite naturally asks: “Is it possible to eliminate this ‘trial’ procedure?” The answer to this question is in the affirmative. In the approach to the problem, the human factor of intuition is removed from spatial treatment-planning as much as possible, and th...
