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