Lorentz Center Workshop: Artefacts in X-ray Tomography

Dates: 
Friday, January 9, 2015 - 17:45
Event Description: 

This Lorentz Center Workshop aims to initiate an in-depth discussion on the various artefacts that arise in X-ray tomography. The mismatch between the models based on theoretical X-ray physics and the real-world experiments plays a crucial role in making advanced algorithms work well on complex measurement data. The program will consist of a broad lecture program in the mornings and focused discussions in the afternoons, where the participants will work in small discussion groups, based on concrete cases of artefact-problems in synchrotron practice. A series of case descriptions (including explanations, current reconstruction strategy, and experimental datasets) will be used to guide the discussion.

This workshop especially (but not exclusively) targets young researchers at the PhD and postdoc stage. Women are specifically encouraged to participate. The registration will close on Monday December 1st. As the capacity of the workshop accommodation is limited to 55 participants, we may need to make a selection based on the total number of registrants. You will be informed of the selection by Monday December 8th. We will try to obtain a balanced representation of all fields involved in this topic (experimental, mathematical, computational, …). The COST budget allows to provide full or partial reimbursement (travel/hotel/meals) for a substantial number of participants. For the reimbursement, priority will be given to participants at the PhD and postdoc stage.

Lorentz Workshop on “Artefacts in X-ray tomography”, Leiden, 9-13 February 2015.

Dates: 
Monday, February 9, 2015 - 23:15 to Friday, February 13, 2015 - 23:30
Event Description: 

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...

Event Description: 

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.

International Symposium on Image and Signal Processing and Analysis

Dates: 
Monday, September 7, 2015 - 18:00
Event Description: 

In recent years, significant advances have been made in the field of X-ray imaging. Modern X-ray scanners can collect a huge amount of data which is processed by custom-tailored reconstruction algorithms. Reconstructed images are then analysed with advanced image processing techniques. As a result, faster image formation, increased spatial and temporal resolution, and more detailed image analysis can be achieved. The aim of the special session is to investigate the tomographic process from the viewpoint of the data processed. The topic of the special session includes, but is not limited to

  • linear and non-linear modeling methods of X-ray imaging devices;
  • novel type and/or custom-tailored image reconstruction algorithms;
  • handling with noisy, imprecise or missing data in tomography;
  • collecting and exploiting prior information in image reconstruction;
  • data collection, analysis and visualization in reconstruction tomography;
  • machine learning methods in tomography;
  • optimization in tomography;
  • applications in absorption-, phase-, fluorescent-, and diffraction-contrast tomography.

mini-workshop on “Finding approaches to eliminate artefacts in x-ray phase contrast computed tomography”, September 16-18 2015, UCL London

Dates: 
Wednesday, September 16, 2015 - 23:45
Event Description: 

X-ray phase contrast (PC) computed tomography (CT) has been heavily investigated over the last two decades. It holds potential to overcome the major limiting factor of conventional CT: poor contrast for soft biological tissues. This is because contrast in PC-CT is driven by phase effects rather than attenuation ones, which can be several orders of magnitude stronger than the latter. PC-CT is typically implemented using propagation-based, crystal-based or grating-based approaches. These methods, however, rely either on spatially or temporarily coherent or quasi-parallel beams. These conditions are only met at synchrotrons, or, to some extent, by micro-focal x-ray tubes. The use of synchrotrons and micro-focal x-ray tubes is not suited to many practical applications due to accessibility and x-ray flux constraints, respectively. At UCL, new approaches to PC-CT have been developed, named edge illumination PC-CT, which has been demonstrated in several instances to work well with x-ray tubes with relatively large focal spots, i.e. in a scenario that is closer to practical reality.

This workshop was primarily aimed at a) identifying the origin of artefacts in edge illumination PC-CT images and b) at finding approaches towards their elimination, but also at c) gaining insight about image acquisition and reconstruction techniques employed by other groups, and d) at identifying possible future collaborations.
