Multimodal Imaging and Image Fusion

Abstract

In multimodal imaging diverse imaging techniques are applied to the same subject usually within a limited time frame in order to capture the same functional, morphologic, and metabolic state of the subject. The historical most compelling need for multimodal imaging stems from the requirement to match functional or metabolic information captured with, e.g., positron emission tomography (PET) or single-photon emission computed tomography (SPECT) with morphological information about the subject obtained from computed tomography (CT) or magnetic resonance imaging (MRI).
