Abstract
The paper is devoted to a new method of time-domain lifetime fluorescence molecular tomography. It is based on the use of early arriving diffuse photons and original measurement data, which are determined for the individual time gates of the diffuse temporal responses for fluorescence and exiting radiation. The paper presents in short the theoretical foundation of the method and describes a numerical experiment on the separate reconstruction of fluorophore absorption coefficient and fluorescence lifetime for 3D reflectance geometry that is suitable for small animal imaging. We show our first reconstruction results for the 3D scattering object region 11×11×8 mm3 in size with two spherical fluorescent inclusions 1 mm in diameter. The ways how to improve these results in the future are discussed.
