TV regularization for optical tomography based on the radiative transport equation has been studied in , where inexact Gauss-Newton method is used to solve the TV regularization problem.
The light propagation in tissues is described by the radiative transport equation
Gao and Zhao  analyzed the numerical solver for radiative transport equation.
"Analysis of a numerical solver for radiative transport equation, "Mathematics of Computation, 82(281): 153-172.
IAD is an accurate solution of the radiative transport
equation for all albedos, all optical depths, and all phase functions and can be applied to any medium for which the radiative transport
equation is valid .
This method is called inverse adding-doubling (IAD): "inverse" to imply a reversal of the usual process of calculating reflection and transmission from optical properties and "adding-doubling" to indicate the method used to solve the radiative transport
Krugel (Max Planck Institute for Radioastronomy) gives students and professionals a solid background in working with the concepts and practicalities of space dust, including considering the dielectric permeability, evaluating grain cross sections, dealing with very small and very big particles, using case studies of Mie calculus, determining the structure and composition of dust, calculating dust radiation, placing the behavior of dust within its environmental contexts, determining polycyclic aromatic hydrocarbons and spectral features, studying reddening and dust models and radiative transport
, and recording spectral energy distribution of dusty objects.
(0.15 m) diameter luminaire with horizontal lamps (#7) not only facilitated convection to the plenum, as discussed in the preceding paragraph, but also resulted in significant radiative transport
to the plenum.
