Edge-promoting reconstruction of absorption and diffusivity in optical tomography
Antti Hannukainen, Lauri Harhanen, Nuutti Hyvönen +1
In optical tomography a physical body is illuminated with near-infrared light and the resulting outward photon flux is measured at the object boundary. The goal is to reconstruct i…
Edge-enhancing reconstruction algorithm for three-dimensional electrical impedance tomography
Lauri Harhanen, Nuutti Hyvönen, Helle Majander +1
Electrical impedance tomography is an imaging modality for extracting information on the conductivity distribution inside a physical body from boundary measurements of current and…
A priorconditioned LSQR algorithm for linear ill-posed problems with edge-preserving regularization
Simon R. Arridge, Marta M. Betcke, Lauri Harhanen
This article presents a method for solving large-scale linear inverse problems regular- ized with a nonlinear, edge-preserving penalty term such as the total variation or Perona-Ma…
