Cli Parametric Images#

Command-line interface (CLI) for generating PET parametric images using graphical analysis of Time-Activity Curves (TACs).

This module provides a CLI to work with the parametric_images module. It uses argparse to handle command-line arguments.

The user must provide:

  • Input TAC file path

  • Path to the 4D PET image file

  • Threshold in minutes (below which data points will be not be used for fitting)

  • The method name for generating the images. Supported methods are ‘patlak’, ‘logan’, or ‘alt-logan’.

  • Output directory where the parametric images will be saved

An optional filename prefix for the output files can also be supplied.

This script uses the :class:’petpal.parametric_images.GraphicalAnalysisParametricImage’ class to calculate and save the images.

Example

petpal-parametric-image --input-tac-path /path/to/input.tac --input-image-path /path/to/pet4D.img --threshold-in-mins 30.0 --method-name patlak --output-directory ./images --output-filename-prefix image
