| 中文摘要: |
| 立体定向放射治疗的剂量累积过程和二维CT图像重建中的直接反投影过程是类似的。本文提出一种用图像描述放射治疗计划的方法,并利用直接反投影图像的重建算法进行放射治疗计划设计。 计算机仿真实验的结果证明了该方法的可行性。 |
| 英文摘要: |
| This procedure of dose distribution in radiotherapy treatment was similar to that of the back-projection in 2D CT image reconstruction. A method of image processing was developed to describe the radiotherapy treatment planning, and the back-projection reconstruction method was used to program the radiotherapy treatment planning. Computer simulation results validate the feasibility of this method. |
