Functional imaging (or physiological imaging) is a medical imaging technique of detecting or measuring changes in metabolism, blood flow, regional chemical composition, and absorption.
As opposed to structural imaging, functional imaging centers on revealing physiological activities within a certain tissue or organ by employing medical image modalities that very often …
Functional imaging focuses on the analysis of physiological activities within a certain tissue or organ. Very often, it deals with the analysis of changes in perfusion, glucose concentration, etc. This is done by employing different imaging modalities, such as: spectral imaging, optical coherence tomography, photoacoustic imaging, etc.
