COST Training School on Algebraic Reconstruction Methods in Tomography

COST Training School on Algebraic Reconstruction Methods in Tomography

April 4–6, 2016, Technical University of Denmark.

This training school is part of the EXTREMA COST Action MP1207. It takes place over 3 days at DTU, the Technical University of Denmark, located north of Copenhagen.

Course Description

Algebraic reconstruction methods for computed tomography (CT), such as ART (Kaczmarz's method) and SIRT, provide an interesting alternative to “analytical” methods, such as filtered back projection. They allow more flexibility in the forward model as well as easy incorporation of constraints on the reconstruction – at the expense of longer computing times.

This training school is aimed at participants who are interested in the formulation, implementation, and use of algebraic iterative reconstruction methods. We give a rigorous mathematical description of the reconstruction methods, the associated algebraic models, and the underlying linear algebra, followed by hands-on MATLAB® computer exercises that illustrate these methods. The goal is that the participants will get a basic understanding of the formulation, implementation, and use of the algebraic methods, and thus be able to use them for their own CT problems.

The participants are expected to be familiar with computed tomography and filtered back projection, with MATLAB, and with basic aspects of linear algebra, and they must bring their own laptop.

The training school is arranged back-to-back with the workshop HD-Tomo Days on modern tomographic imaging methods and numerical solution techniques built on regularization, optimization, and PDE anaysis.

Monday, April 4 – Basic Concepts and Methods (Per Christian Hansen, DTU Compute)

Tuesday, April 5 – Large-Scale Aspects (Willem Jan Palenstijn, CWI Centrum Wiskunde & Informatica) Wednesday, April 6 – State-of-the-Art Imaging Methods (joint with the HD-Tomo Days workshop) Participants are encouraged to stay the whole week and seize the opportunity to learn about several different approaches to tomographic reconstruction.

Practical Issues

Meals. Lunch, coffee, tea and refreshments are provided by us. Please indicate any dietary restricions on the registration page.

Travel, accomodation, and reimbursement. Participants must arrange travel and accommodation themselves. For more practical information (the venue, getting to DTU, and suggestions for hotels) please refer to this page for the workshop. Participants of the training school from outside Denmark will be partially reimbursed by COST (more information later).
