BTXRD
BTXRD is a multicenter bone radiograph dataset containing normal bones and primary bone tumors. It supports tumor classification, localization and segmentation using global labels, bounding boxes and pixel-level masks.
BTXRD is publicly downloadable from Figshare without registration under the Creative Commons Attribution 4.0 International license (CC BY 4.0), which permits commercial reuse with attribution.
The dataset contains 3,746 radiographs: 1,879 normal images, 1,525 benign-tumor images and 342 malignant-tumor images. Each tumor image has a segmentation mask and bounding box, while image-level metadata include age, gender, anatomical location and projection. Images cover upper limbs, lower limbs and the pelvis. Multiple images may belong to the same lesion, so a unique-subject count cannot be inferred.
