摘要
射野方向观视是三维放射治疗计划系统中重要的射野设计工具。为增强其效果,现通过图像融合,将轮廓线构建的三维表面图像融入到DRR中。其中DRR由光线跟踪生成,三维表面由OpenGL库生成。结果表明,能有效突出射野方向观视中的感兴趣部位。
BEV is an important implement to design fields in radiotherapy treatment planning system （TPS）. To improve BEV＇s effect, the surface built by contours was melted into digitally reconstructed radiographs （DRR） by applying image fusion. DRR was created by raytracing, and surface was built by the library of OpenGL. The result shows tissues with interest are strengthened significantly.
