研究目的:

基于以往鼻咽癌患者的CT影像及对应的放射治疗计划数据,构建并训练一个自动化放疗剂量预测的深度学习模型,通过对模型预测结果与实际临床放疗剂量分布及多个现有剂量预测方法的对比分析,验证该模型在预测鼻咽癌患者放疗剂量分布方面的准确性和可行性。通过计算DVH曲线等临床剂量指标,比较模型预测结果与实际临床计划剂量的差异,并在多个不同病例条件下验证深度学习剂量预测模型的一致性与可靠性。评价模型预测结果的临床剂量学指标(如D95、Dmean、Dmax等),结合不同靶区和危及器官的剂量分布特征,分析其在放疗质量控制与计划优化中的潜在应用价值。  

Objectives of Study:

Based on CT images and corresponding radiotherapy planning data from previous nasopharyngeal carcinoma patients, construct and train a deep learning model for automated radiotherapy dose prediction. Through comparative analysis between the model's predictions and actual clinical radiotherapy dose distributions as well as multiple existing dose prediction methods, verify the accuracy and feasibility of this model in predicting radiotherapy dose distributions for nasopharyngeal carcinoma patients. By calculating clinical dose metrics such as DVH curves, compare the differences between the model's predictions and actual clinical plan doses, and validate the consistency and reliability of the deep learning dose prediction model under various case conditions. Evaluate clinical dosimetric metrics (such as D95, Dmean, Dmax, etc.) for model prediction results, and analyze their potential application value in radiotherapy quality control and plan optimization by combining dose distribution characteristics of different target volumes and organs at risk.
