Abstract :
Fluorescence tomography is an emerging tool for functional and molecular imaging of tissues. Inversion is however complicated by the high scattering that photons experience when propagating through tissue that reduces resolution. While continuous wave systems offer implementation simplicity, time-resolved systems offer the ability to improve resolution and reduce the ill-posed nature of the inverse problem by using early arriving photons. We present an overview of our current progress in complete-angle illumination early photon tomography and present the associated data processing steps employed for early photon inversions.
