CT-RTSTRUCT-RTDOSE-RTPLAN Sets of Head and Neck Cancers Treated with Identical Prescriptions using IMRT: An Open Dataset for Deep Learning in Treatment Planning

This collection includes data from 211 patients who presented with head and neck cancer and underwent treatment with external beam radiation therapy at a single institution utilizing 6 megavolts (MV) Intensity Modulated Radiation Therapy (IMRT) delivered via a linear accelerator. All patients received identical prescriptions of 70 Gray (Gy) in 33 fractions for the primary planning target volume (PTV), with additional sub-targets (PTV 54 Gy, PTV 56 Gy, PTV 57 Gy, PTV 60 Gy, PTV 63 Gy, PTV 66 Gy) optionally included or excluded. This dataset contains for each patient the complete radiotherapy treatment in DICOM format, including the planning computed tomography (CT) images, expert-defined radiotherapy structures (RTSTRUCT), radiotherapy plan (RTPLAN), and the calculated treatment dose (RTDOSE). To facilitate efficient data extraction, 26 high-priority organ-at-risk (OAR) contours were standardized by renaming them in the RTSTRUCT file, ensuring consistent nomenclature across the dataset.

本数据集收录了211名头颈部肿瘤患者的诊疗数据，所有患者均在单一医疗机构接受外照射放疗（external beam radiation therapy），治疗采用直线加速器（linear accelerator）递送的6兆伏（megavolts, MV）调强放射治疗（Intensity Modulated Radiation Therapy, IMRT）。所有患者的原发计划靶区（planning target volume, PTV）均采用统一处方：33次分割照射，总剂量70戈瑞（Gray, Gy）；此外可选择性包含或排除多个亚靶区，具体包括PTV 54 Gy、PTV 56 Gy、PTV 57 Gy、PTV 60 Gy、PTV 63 Gy、PTV 66 Gy。本数据集为每位患者存储了DICOM格式的完整放疗治疗数据，涵盖计划计算机断层扫描（computed tomography, CT）图像、专家勾画的放疗结构文件（RTSTRUCT）、放疗计划文件（RTPLAN）以及计算得到的治疗剂量文件（RTDOSE）。为提升数据提取效率，研究人员对RTSTRUCT文件中的26个高优先级危及器官（organ-at-risk, OAR）轮廓进行了统一重命名，确保数据集内的命名规范保持一致。
