作者介绍了 3 年使用数字重建放射线照片 (DRR) 进行放射治疗计划和验证的经验。与模拟胶片（SF）进行比较，以说明DRR相对于SF的优势。重点是使用适当的设备和应用正确的技术。简要介绍CT成像原理，说明CT软件的操作以及轴向层和DRR图像显示的优化。重点放在临床知识的应用上，以提高 DRR 的实用性和技术质量。给出了说明性例子。
The authors present 3 years of experience in using digitally reconstructed radiographs (DRR) for radiotherapy planning and verification. Comparison is made with simulation film (SF), to illustrate the advantages of DRR over SF. Emphasis is placed on using the appropriate equipment and applying the correct technique. A brief discourse on the principle of CT imaging is presented to illustrate the operation of CT software and optimization of image display for axial slices and DRR. Emphasis is placed on the application of clinical knowledge to enhance the usefulness, as well as the technical quality, of the DRR. Illustrative examples are given.
