CANDID-PTX

19,237 anonymized adult chest x-ray datasets in 1024 x 1024 pixel DICOM format with corresponding anonymized free-text reports from Dunedin Hospital, New Zealand between 2010 - 2020. Images were manually annotated by RANZCR radiology trainee and radiologists with respect to pneumothorax, acute rib fracture, and chest tubes. Segmentation annotations were converted to run-length-coded (RLE) format in csv files. In the provided metadata, image filenames contain patient index (enabling analysis requiring patient grouping of images), as well as anonymized date of acquisition information where the temporal relationship between images is preserved.Unfortunately, since Feb 2024, the New Zealand government is changing the data governance on datasets used for AI development and this affects the process of how the CANDID PTX dataset is to be accessed by the external users. Therefore, the CANDID PTX dataset is not available for access by users outside Health New Zealand. Further notice of access will be updated here should access by external users be reopened.

本数据集包含19237份经匿名化处理的成人胸部X射线影像，分辨率为1024×1024像素，格式为DICOM（医学数字成像与通信），配套对应匿名化自由文本报告，采集自新西兰达尼丁医院，时间跨度为2010年至2020年。所有影像均由澳大利亚新西兰皇家放射科医师学院（RANZCR）的放射科规培医师及执业放射科医师，针对气胸（Pneumothorax）、急性肋骨骨折（Acute Rib Fracture）及胸腔引流管（Chest Tubes）三类影像征象完成人工标注。分割标注已被转换为CSV文件中的游程编码（Run-Length Encoding，RLE）格式。在提供的元数据中，影像文件名包含患者索引信息，可支持需按患者分组影像的分析研究；同时保留了可体现影像间时间关联关系的匿名化采集日期信息。如需获取该数据集，需完成两项伦理培训流程：1. 修读在线伦理课程：访问链接https://globalhealthtrainingcentre.tghn.org/ethics-and-best-practices-sharing-individual-level-data-clinical-and-public-health-research/，需先注册账号以免费修读该在线伦理课程。完成课程测验后，请将课程证书发送至邮箱[e-mail]。2. 签署数据使用协议：该协议可通过Data Use Agreement.pdf获取。签署完成后，请同样将签署后的协议副本发送至邮箱[e-mail]。完成上述两项步骤后，您将收到数据集下载链接。
