1. A method for estimating kinetic parameters from image data, the method comprising:
- providing a model of kinetic contributions from first and second physiological regions;
grouping voxels of the image data into first and second groups;
determining an average value of the factors associated with the first group;
incorporating the average value into the model; and
estimating the kinetic parameters based on the model.

Abstract
A method for processing image data includes estimating initial factor images from image data, transforming the estimated initial factor images by a transformation variable to obtain transformed factor images, providing an objective function that is a function of the transformed factor images, and minimizing the objective function to obtain unique factor images from the estimated initial factor images.
