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.To access the data, an ethics training process is required and is divided into 2 steps:1. An online ethics course at https://globalhealthtrainingcentre.tghn.org/ethics-and-best-practices-sharing-individual-level-data-clinical-and-public-health-research/. You will need to register an account to be able to take the free online ethics course. Once you finished the course quiz, please send the course certificate to [e-mail].2. Signing the Data Use Agreement. It can be accessed at Data Use Agreement.pdf. Once you signed the Data Use Agreement, please also send the signed copy to [e-mail] you have successfully completed both of above steps, you will receive a link to download the dataset.

19237份经匿名化处理的成人胸部X射线数据集，分辨率为1024×1024像素，格式为DICOM（Digital Imaging and Communications in Medicine），配套采集自新西兰达尼丁医院2010年至2020年的匿名化自由文本报告。
所有影像均由澳大利亚新西兰皇家放射医师学院（RANZCR）的放射科规培医师及专职放射科医师，针对气胸、急性肋骨骨折及胸管置入情况开展手动标注。
分割标注已被转换为CSV文件中的运行长度编码（RLE）格式。
在配套提供的元数据中，影像文件名包含患者索引信息（可支持需按患者对影像进行分组的分析场景），同时保留了可反映影像间时间关联关系的匿名化拍摄日期信息。
