Cancer Imaging Phenomics Toolkit (CaPTk)  1.6.1
Miscellaneous: PCA Volume Extraction

This application extracts the principal components from DSC-MRI scans as mentioned in [1].

REQUIREMENTS: A single DSC-MRI image and a mask for which the measurements will be extracted.


  1. Load a DSC-MRI in CaPTk and the mask (Label:1) defining the voxels to extract the measurements.
  2. Launch the application from "Applications" -> "PCA Volume Extraction".
  3. Specify the number of principal components required and the output directory.
  4. Press "Confirm" button.
  5. The principal components will be extracted at the specified location and also loaded in CaPTk (~5 minutes).
