PAXRAY Dataset

The authors of the PAXRAY: A Projected dataset for the segmentation of Anatomical structures in X-RAY data present a novel pipeline for generating annotations to assist the CXR (chest X-ray) domain by extracting information from more easily annotatable CTs (computed tomography scans). They provide a densely labeled fine-grained dataset for anatomy segmentation, encompassing both frontal and lateral views. The methodology leverages the consistency of anatomy across imaging domains, utilizing established models in the CT domain to generate annotations automatically. These annotations and corresponding images are then projected to 2D, mimicking the X-ray domain.

PAXRAY：X射线解剖结构分割的投影数据集的作者们提出了一种新颖的流程，以生成标注以辅助 CXR（胸部X射线）领域。该流程通过从易于标注的 CT（计算机断层扫描）中提取信息来实现。他们提供了一组密集标注的精细粒度解剖分割数据集，包括正面和侧面视图。该方法利用了影像学领域解剖结构的一致性，利用 CT 领域中已建立的模型自动生成标注。随后，这些标注及其对应图像被投影到二维空间，模拟 X射线领域。
