The University Hospital of Basel
The University Hospital of Basel leads TotalSegmentator, an open-source research initiative dedicated to advancing clinically relevant medical image segmentation for the scientific community.

Breast cancer affects one in eight women worldwide.
Accurately segmenting breast carcinoma remains challenging due to variability in breast density, imaging conditions, and the need to reliably distinguish malignant tumours from benign findings.

Project Goals
- Enable reliable segmentation of breast carcinoma across diverse breast densities and imaging conditions.
- Support radiologists and researchers in differentiating malignant tumours from benign findings.
- Contribute clinically reliable annotated datasets to strengthen open-source breast imaging models.
