The present invention provides systems and methods for obtaining a threedimensional (3D) representation of one or more light sources inside a sample such as a mammal. Mammalian tissue is a turbid medium meaning that photons , are both absorbed and scattered as they propagate through tissue. In the case where scattering is large compared with absorption such as red to near-, infrared light passing through tissue the transport of light within the , sample is described by diffusion theory. Using imaging data and computerimplemented photon diffusion models, embodiments of the present invention produce a 3D representation of the light sources inside a sample such as a 3D , location, size, and …

Why it's free to use
- Filed July 15, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 15, 2023.
