Cancer Imaging Phenomics Toolkit (CaPTk)  1.9.0
Breast Cancer: Texture Feature Extraction

This application extracts radiomic features related to breast cancer risk, as described in the paper [1]. It is based upon LIBRA for segmentation of the breast and the lattice-based mode of Feature Extraction backend to perform radiomic feature calculations.


  • 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 (required only in GUI).


  1. Load the FFDM image using the 'File -> Load -> Images' menu option.
  2. Launch Breast Texture Feature Extraction using the 'Applications -> [Breast Cancer] Texture Pipeline' menu option.
  3. Specify the output directory.


  • output.csv: CSV file with the extracted radiomic features.
  • featureMap/: Folder of feature maps, one for each radiomic feature, reflecting the spatial feature distributions within the breast.
    • This application is also available as with a stand-alone CLI for data analysts to build pipelines around, using the following example command:
      ${CaPTk_InstallDir}/bin/BreastTexturePipeline.exe -i C:/input/image.dcm -o C:/outputDir -d 1
