Overview of MRI, fMRI, and DTI modalities

Explanation of data types extracted from each modality

Introduction to applications of curve, volume, and surface data

Abstract

This article is based on the first chapter of book Chung (2013), where brain and medical images are introduced. The most widely used brain imaging modalities are magnetic resonance images (MRI), functional-MRI (fMRI) and diffusion tensor images (DTI). A brief introduction to each imaging modality is explained. Further, we explain what kind of curve, volume and surface data that can be extracted from each modality.
