public class AlgorithmDTI2EGFA
extends AlgorithmBase

Algorithm requires input of a Diffusion Tensor Image to calculate an Apparent Diffusion Coefficient Image, Functional Anisotropy Image, Color Image, Eigen Value Image, Eigen Vector Image, Relative Anisotropy Image, Trace Image, and Volume Ratio Image This algorithm works in conjunction with AlgorithmDTITract to create the MIPAV DTI Fiber Tracking/ Statistics Dialog See: Introduction to Diffusion Tensor Imaging, by Susumu Mori
