內容簡介：

本书从调强放疗的步骤入手，概括介绍常用的放疗设备、照射方式、放疗目的、放疗的生物学原理等；重点介绍调强放疗中的计算机应用技术，涉及剂量计算模型、放疗计划系统中的可行性问题，以及线性和非线性规划模型、放射生物学模型、带有剂量体积约束的规划模型、多目标规划模型、照射角度选择优化模型等。此外，本书对通量图的生成和调制、基于机器跳数的平滑方法和双向叶片运动通量图平滑模型等进行研究；讨论自动勾画的意义、需求和定义等，介绍阈值分割算法、区域分割算法、分水岭分割算法和马尔可夫随机场分割算法等常见的图像分割算法，重点介绍一种加入区域信息的测地线活动轮廓模型、一种改进的V-Net 模型和一种基于等效生物剂量和硬件约束的一体化逆向计划模型，并介绍凸优化求解和剂量验证等。本书介绍的内容涉及面广，有助于读者了解调强放疗中的计算机应用技术，适合作为高等学校医学影像处理相关专业研究生和高年级本科生的教材，也适合相关科研人员和对调强放疗技术感兴趣的读者阅读。
