摘要
放射治疗需要制定周密的计划，可视化技术对制定放疗计划具有重要作用。本文以VC＋＋6．0为工具，基于VTK开发了多种可视化算法，研究了放射治疗计划中的可视化技术。利用OpenGL图形库模拟了虚拟放疗环境，研究了一种实时的放射治疗设备碰撞检测方法，可以检测计划中潜在的碰撞，以确保放射治疗计划的安全实施。试验表明，此种可视化方法有助于医生制定合理高效的放射治疗计划。
A precision planning is necessary for radiotherapy, and the visualization technologies are effective for the treatment planning of radiotherapy. Under VC＋＋ 6.0 environment, the authors completed some algorithms based on VTK, and introduced some algorithms related to visualization technologies. To guarantee the execution of radiotherapy planning, the authors studied a kind of method for performing real-time collision detection between radiotherapy equipments. The authors also simulated the virtual radiotherapy environment based on the OpenGL graphics library to detect the potential collision. Experiments showed that the visualization of treatment planning was very useful for the design of treatment planning.
