Diffuse Optical Imaging

Definition: Diffuse Optical Imaging (DOI) measures multiple scattered light and inverts this data to spatially resolve optical properties of a diffuse medium, generally by utilizing a reconstruction algorithm. Optical properties, in turn, are used to compute physiological parameters (e.g., hemoglobin concentration). Diffuse optical imaging covers both Diffuse Optical Topography (reconstruction in 2D), and Diffuse Optical Tomography (reconstruction in 3D).

Alternative definition: Diffuse Correlation Spectroscopy (DCS) uses the fluctuation statistics of diffuse, coherent light to measure microvascular blood flow in tissues.
