dcemriS4 (version 0.51)

dcemriS4-package: dcemri: A Package for Medical Image Analysis (S4 implementation)

Description

A collection of routines and documentation that allows one to perform a quantitative analysis of dynamic contrast-enhanced or diffusion-weighted MRI data. Medical imaging data should be organized using either the Analyze or NIfTI data formats.
