Fast numerical modelling of light transport inside diffusive media and reconstruction with TOAST++ open source software

Abstract

Fast numerical modelling of light transport inside diffusive media and reconstruction with TOAST++ open source software.

Toast++ is an ongoing CMIC software development for numerical modelling and nonlinear image reconstruction that has recently been turned into an open-source project.

The main application of the software is in diffuse optical tomography (DOT). Toast++ uses a finite element model for simulating light transport in heterogeneous scattering media, which is embedded in a model-based iterative optimisation framework for recovering the spatial distribution of optical parameters within a volume of tissue, given boundary measurements of light transillumination.

I will give an overview of the capabilities of the system, and highlight some of the most recent developments, in particular the integration of fast distributed and GPU solvers. I will show examples for applying Toast++ to reconstruction problems in DOT using its Matlab and Python interfaces.
