Tomographic X-ray data of a lotus root filled with attenuating objects
Tatiana A. Bubba, Andreas Hauptmann, Simo Huotari +2
This is the documentation of the tomographic X-ray data of a lotus root, filled with four different attenuating objects, of different sizes. Data are available at www.fips.fi/datas…
Propagation and recovery of singularities in the inverse conductivity problem
Allan Greenleaf, Matti Lassas, Matteo Santacesaria +2
The ill-posedness of Calderón's inverse conductivity problem, responsible for the poor spatial resolution of Electrical Impedance Tomography (EIT), has been an impetus for the deve…
Shape recovery from sparse tomographic X-ray data
Heikki Haario, Aki Kallonen, Marko Laine +3
A two-dimensional tomographic problem is studied. The target is assumed to be a homogeneous object bounded by a smooth curve. A Non Uniform Rational Basis Splines (NURBS) curve is…
Direct inversion from partial-boundary data in electrical impedance tomography
Andreas Hauptmann, Matteo Santacesaria, Samuli Siltanen
In Electrical Impedance Tomography (EIT) one wants to image the conductivity distribution of a body from current and voltage measurements carried out on its boundary. In this paper…
Photographic dataset: random peppercorns
Teemu Helenius, Samuli Siltanen
This is a photographic dataset collected for testing image processing algorithms. The idea is to have sets of different but statistically similar images. In this work the images sh…
The D-bar Method for Diffuse Optical Tomography: a computational study
Janne P. Tamminen, Tanja Tarvainen, Samuli Siltanen
The D-bar method at negative energy is numerically implemented. Using the method we are able to numerically reconstruct potentials and investigate exceptional points at negative en…
