Diffuse optical tomography based on time-resolved compressive sensing

International audienceDiffuse Optical Tomography (DOT) can be described as a highly multidimensional problem generating a huge data set with long acquisition/computational times. Biological tissue behaves as a low pass filter in the spatial frequency domain, hence compressive sensing approaches, based on both patterned illumination and detection, are useful to reduce the data set while preserving the information content. In this work, a multiple-view time-domain compressed sensing DOT system is presented and experimentally validated on non-planar tissue-mimicking phantoms containing absorbing and scattering inclusions. The dependence of system imaging capability with the choice of illumination/detection patterns, views and temporal gates will be discussed
