The ESRF workshop was intended to bring together experimental and computational scientists involved in advanced X-ray tomography in the state-of-the-art synchrotron X-ray imaging environment of ESRF.
The program centered around three challenging topics, for which datasets have been made available before the workshop: (i) combined phase retrieval and tomography; (ii) region-of-interest tomography; (iii) limited data and low-dose tomography. A unique feature of this workshop was the hands-on program on the first day, where the participants experienced the actual imaging process at various synchrotron tomography beamlines.
Local organizers: Wolfgang Ludwig, Peter Cloetens, Claudio Ferrero

The EXTREMA COST Action provided reimbursement for 19 participants, covering travel and lodging costs and Local Organizer Support, for a total of € 17.762,80.

This meeting combined lectures and discussion on a broad range of theoretical, computational and experimental aspects of tomography. Several EXTREMA members participated in the meeting, from various backgrounds. The meeting was not COST-only, and as such it allowed to introduce our network to a partially new audience. MP1207 provided participant reimbursement for 7 participants and Local Organiser Support.

Local organizers: Paolo Dulio and Carla Peri

The EXTREMA COST Action provided reimbursement for 14 participants, covering travel and lodging costs and Local Organizer Support, for a total of € 11.857,33.

This dedicated EXTREMA training school will take place at the Vision Lab of the University of Antwerp and will be co-organized by CWI, Amsterdam. In a three day program, the trainees are introduced to advanced tomographic reconstruction using the ASTRA toolbox (http://www.astra-toolbox.com), a flexible open source platform for tomography.

The EXTREMA COST Action provides trainee grants for a limited number of participants.

Significant progress has been made in recent years in the ability to perform advanced 3D X-ray imaging for scientific, industrial and medical applications. The quality of such images is often limited by the presence of certain structured distortions, known as “artefacts”. Artefacts can have a broad range of causes, related to the experimental setup, but also to the computations performed on the measured data. The main goal of this Lorentz Center Workshop was to initiate an in-depth discussion on the various artefacts that arise in X-ray tomography.
The workshop brought together around 55 participants from different communities (mathematical, computational, engineering, photonics, experimental) involved in tomography. From the first day and onwards, there was a strong urge among the participants to zoom into concrete problems and exchange experiences related to these problems.
Several discussion groups on selected topics were formed during the week:
1. Region-of-Interest Tomography
2. X-ray micro-CT
3. Full system calibration
4. Fluid flow reconstruction in CT
5. Reconstruction from limited and noisy data
6. Correction for motion introduced during acquisition
7. Quality measures for tomography scans
Before the workshop, Francesco de Carlo compiled a repository of experimental synchrotron datasets that served as a basis for many of the discussions.A particular successful item in the program was the speeddating session, where participants were teamed up in pairs for 3-minute discussions. Although no one knew what to expect, it was highly valued by most participants as a good means of creating new contacts.
As a platform for shaping the newly formed collaborations, a web repository was set up for the different topics treated during the workshop, which can be found at https://confluence.aps.anl.gov/display/XSDLORENTZ2015/Artefacts+in+X-Ray...

The EXTREMA COST Action provided reimbursement for 22 participants, covering travel and lodging costs and Local Organizer Support, for a total of € 20.612,98.

This workshop focused on advances in X-ray imaging exploiting the coherent light 3rd and 4th generation synchrotron light sources, with special attention paid to progresses in image analysis with reference to their application in different research field, from medicine, biology, cultural heritage till new materials.

The Industrial Tomography Workshop (into2014) is a scientific conference that was organized at the University of Helsinki, Finland, taking place on October 13-15, 2014. The workshop brought together academic and industrial experts on tomography with a two-fold goal:
1. Transferring the latest scientific research results into commercial research and development pipeline, and
2. Educate the academic community about the current industrial needs related to tomography.
The background of the academic participants is physics, mathematics, signal and image processing, and engineering. Industrial representatives are invited from several business areas, including medical imaging and nondestructive testing technology.

The local organizing institutions are Department of Mathematics and Statistics of University of Helsinki and the Finnish Inverse Problems Society (http://www.fips.fi).
The annual Management Committee meeting of the EXTREMA COST Action took place as part of this workshop.
Local Organiser: Samuli Siltanen (University of Helsinki, Finland)
The EXTREMA COST Action provided reimbursement for 30 participants, covering travel and lodging costs and Local Organizer Support, for a total of € 29.727,25.

This meeting brings together participants from the COST Actions MP1203 (X-ray metrology) and MP1207 (X-ray tomography) to explore the boundaries between the two topics and find common interests. MP1207 will provide participant reimbursement for 7 participants (all members of EXTREMA) and Local Organiser Support.

This meeting combined lectures and discussion on a broad range of theoretical, computational and experimental aspects of tomography. Several EXTREMA members participated in the meeting, from various backgrounds. The meeting was not COST-only, and as such it allowed to introduce our network to a partially new audience. MP1207 provided participant reimbursement for 7 participants and Local Organiser Support.

This special EXTREMA session on combinatorial aspects of tomography was embedded in the 27th conference of the European Chapter on Combinatorial Optimization. It was a 1-day event, where researchers from theoretical aspects of tomography and more practice-oriented scientists presented their work and had discussions, aimed at finding common interests and setting new directions for joint research. MP1207 provided participant reimbursement for 7 participants and Local Organiser Support.

This dedicated EXTREMA training school took place at the Vision Lab of the University of Antwerp. In a three day program the trainees were introduced to performing advanced tomographic reconstruction using the ASTRA toolbox, a flexible open source platform for tomography. MP1207 provided trainee grants for 15 participants, reimbursement for two trainers, and Local Organiser Support.
