Abstract
We present the first three-dimensional tomographic reconstruction scheme for general geometries and arbitrary spatial material distributions that is based on the equation of radiative transfer. This scheme builds on the concept of model-based iterative image reconstruction, in which a forward model provides prediction of detector readings, and a gradient-based updating scheme minimizes an objective function. The gradient of the objective function is found by employing an adjoint differentiation method.
