Cancer Imaging Phenomics Toolkit (CaPTk)  1.9.0
Breast Cancer: Breast Segmentation

This application uses LIBRA [1] to extract the breast region in the loaded image and is only availabe via the GUI (the Breast Texture Feature Extraction can be used to generate a mask and perform radiomic analysis via the command line).


  • Raw (i.e., "FOR PROCESSING") or vendor post-processed (i.e., "FOR PRESENTATION") FFDM images.
  • FFDM vendors currently supported: Hologic and GE Healthcare.
  • Each image stored in a separate folder.


  1. Load the FFDM image using the 'File -> Load -> Images' menu option.
  2. Launch LIBRA using the 'Applications -> Breast Segmentation' menu option.
  3. Output, i.e., breast mask, is loaded automatically.
