Diffuse optical tomography by using time-resolved single pixel camera

Abstract

© 2015 SPIE. Diffuse Optical Tomography (DOT) and Fluorescence Molecular Tomography (FMT) generally require a huge data set which poses severe limits to acquisition and computational time, especially with a multidimensional data set. The highly scattering behavior of biological tissue leads to a low bandwidth of the information spatial distribution and hence the sampling can be preferably carried out in the spatial frequency source/detector space. In this work, a time-resolved single pixel camera scheme combined with structured light illumination is presented and experimentally validated on phantoms measurements. This approach leads to a significant reduction of the data set while preserving the information content.
