Dataset for multicenter comparison of measures for quantitative evaluation of contouring in radiotherapy

This dataset was created to perform a comparison of tools used for the assessment of contouring between different institutions. A survey was conducted between institutions using this dataset, the results of which will be published separately. The dataset consists of two CT images with "test" and "reference" RTSS, for which participants were asked to submit the values for the contouring measures they used. Ground truth measurements are not provided. The first study consists of a synthetic image with synthetic shapes. The second study is based on one case from the AAPM 2017 Thoracic Auto‐Segmentation Challenge dataset, case LTCSC-Test-S1-201, for which an additional "test" contour has been added.

本数据集专为开展不同机构间轮廓评估工具的对比研究而构建。本次研究面向使用该数据集的各机构开展了调研，调研结果将另行发布。数据集包含两份CT图像，分别带有"test"与"reference"放疗结构集（Radiation Therapy Structure Set，RTSS），要求参与者提交其所用轮廓评估指标的数值，且未附带真值测量结果。第一项研究采用带有合成形状的合成CT图像；第二项研究则基于美国医学物理学家协会（American Association of Physicists in Medicine，AAPM）2017年胸部自动分割挑战赛（Thoracic Auto‐Segmentation Challenge）数据集的一例病例LTCSC-Test-S1-201，并为其额外添加了一条"test"轮廓。
