Patient treatment in a medical linear accelerator is characterized by many angular and translational movements of the gantry and couch. The direction and orientation of each treatment beam is specified by a set of gantry, turntable, and collimator angles. It is possible that some selected treatment field configurations will result in gantry/couch or gantry/patient collisions that remain undetected during the treatment planning process. In this work, a digital camera has been used to record all the workable gantry/ patient set-up images, and a Windows programming language is used to edit and display these images on a personal computer for the treatment planner to screen the treatment plans. These graphical displays enable the planner to be aware of any potential collision hazards by an actual visualization of each selected gantry/turntable or gantry/patient angle configuration.
医用直线加速器中的患者治疗以机架和治疗床的多次角度和直线运动为特征。每个治疗束的方向和取向由一组机架、转台和准直器角度指定。某些选定的治疗野配置可能会导致机架/治疗床或机架/患者碰撞，而在治疗计划过程中这些碰撞仍未被检测到。在这项工作中，使用了一台数码相机来记录所有可行的机架/患者设置图像，并使用一种Windows编程语言在个人计算机上编辑和显示这些图像，以便治疗计划者筛选治疗计划。这些图形显示通过对每个选定的机架/转台或机架/患者角度配置进行实际可视化，使计划者能够意识到任何潜在的碰撞危险。
