CBIS-DDSM_1024: processed mammogram PNGs

This repository is a processed subset of full mammogram images from the Curated Breast Imaging Subset of DDSM (CBIS-DDSM), originally published by The Cancer Imaging Archive (TCIA). It is not the original CBIS-DDSM release.

Files in this upload

• 3,086 full mammogram images converted to 8-bit PNG.
• Images organised under train/ and test/, each with cancer/ and not_cancer/ folders based on the source pathology labels.

The original TCIA collection contains DICOM images and CSV metadata. This PNG upload does not provide the original DICOM pixel values or metadata, lesion ROI images, or segmentation masks. For those materials, use the original CBIS-DDSM collection.

Earlier documentation noted that 34 of 3,120 full mammogram images were excluded before conversion. The exclusion criteria and the procedure used to create the train/test folders are not documented here. Verify labels and patient-level separation against the original data before using this copy for evaluation. This dataset is intended for research and education, not clinical diagnosis.
