提出了一个完全三维[癌症]治疗计划的三个特点。波束眼视图从治疗源的角度为用户提供解剖特征的准确再现。源可以移动到相对于患者的任何可行位置，允许选择允许敏感器官被排除在射束之外。在该视图中，可以容易地设计场限定孔径。这种孔径的反投影显示了原始横向CT [计算机断层扫描]切片或重建的矢状或冠状切片的部分，这些部分可能被选定的射束覆盖。通过来自任何期望原点的CT数据的投影提供对准膜模拟，其可用于确认治疗的准确性，以及帮助建立相对于治疗野的边缘的解剖关系。
Three features of a fully 3-dimensional [cancer] treatment planning program are presented. The beam''s-eye-view provides the user with an accurate reproduction of anatomic features from the viewpoint of a treatment source. The source can be moved to any feasible position relative to the patient, permitting a choice which allows sensitive organs to be excluded from the beam. In this view a field defining aperture can readily be designed. Back-projection of such an aperture shows the parts of the original transverse CT [computed tomography] sections, or reconstructed sagittal or coronal sections, which may be covered by the selected beam. Projection through the CT data from any desired origin provides an alignment film simulation which can be used to confirm accuracy of treatment, as well as help establish anatomic relationships relative to the margins of a treatment field.
