Idif Necktangle
===============

.. py:module:: petpal.input_function.idif_necktangle

.. autoapi-nested-parse::

   This module contains a collection of functions to calculate an image-derived input function (IDIF) given a "necktangle".
   "Necktangles" are a 3D rectangular region of interest over the neck to help identify the carotid PET signal.
   This method was developed and provided for use in this software package by `Dr. Karl Friedrichsen <https://orcid.org/0000-0002-9233-1418>`_

   Requires:
       The module relies on the :doc:`numpy <numpy:index>` module.
