Report from CCPi for the Period 8 January 2015 to 24 June 2015

Line: 8 to 8
  The CCP in Tomographic Imaging is progressing and since the last 6-month report, on 8 January 2015, it has built on current activities to deliver new versions of the core codes; both reconstruction and quantitative analysis. The CCPi prioritises the two areas of reconstruction and quantitative analysis and is currently completing the task list from the original network grant proposal (28 August 2015). It aims to provide the UK tomography community with a toolbox of algorithms that increases the quality and level of information that can be extracted by computer tomography. Key components continue to be to increase components, usage, training and software deposits, as well as integration of new iterative methods within the toolkits.

The core team now includes Srikanth Nagella, Barry Searle, Ron Fowler and Evgueni Ovtchinnikov. Evgueni has been brought into the group to assist with CCPi and follow-on networks; this creates the core 1.5 FTE. For the year until Spring 2015 Martin Turner has had an extra role in the secretariat position and, with Erica Yang, has been developing functionality in collaborating with the new IMAT tomographic beamline on the ISIS neutron spallation source. Erica Yang has been given an extension at 0.1 FTE over the following year to continue this role until Spring 2016.

  Formal links are being built with the recently funded CCP PET/MR that employs similar iterative solutions for positron emission tomography (PET) solutions. This has initially involved joint developers' workshops and linking together Working Groups with plans for a shared secretariat role.

  • Reconstruction Core algorithms: optimisation work of the iterative code for Diamond data sets is complete and has been tested on a sequence of reduced projection data from I13. Results have been extended for full sequence as well as creating a Windows GUI for the lab based instruments, with licences created for release to the wider community via a ccpforge download.
  • Quantitative visualisation algorithms: work in quantification and the new Avizo algorithms have been expended with contributions by Erwan Plougonven, extra code from Robert Bradley (MXIF) and a study on beam hardening code (Queen Mary). Case studies (EPSRC formal) are being planned and produced on quantification codes, beam hardening and the flagship activities.
  • Flagship project software outcomes: Daniil Kazantsev reported that 4 papers have been published or in progress (including one in Inverse Problems in Imaging and one on CUDA acceleration) and a final set of code is being developed to compare algorithms for restricted angle reconstruction.

  • A new data archive with community space has been setup on the zenodo website https://zenodo.org/collection/user-ccpi?ln=en The above includes test data sets from Sophia Coban; simple model scans and touchtable presentation data sets for science analysis and for public outreach and dissemination.

  1. ISIS IMAT framework: Srikanth Nagella built the initial testbed for rendering large data sets (2000^3) and a new setup will be operating in September 2015. The initial IMAT demonstrator has a project page at: http://stfc.ac.uk/SCD/research/data/44593.aspx and new publications are planned.

Outreach and networking:

Line: 39 to 39
 
  1. An extended four day Avizo framework developers meeting was held at Manchester hosted by Ali Chirazi (17-20 February 2015).
  2. Touchscreen day at Reading University with NHM (Natural History Museum) was very useful and formed a sub-group (IVG – Interactive Visualisation Group) to promote touch screens for outreach (24 March 2015).

  1. Developers' Day at Manchester Workshop focused on iterative solutions for the XTek machines (such as the released CGLS code) and what is required to get them into regular usage in the labs that use these machines (28 April 2015).

  • Fellowships: Manuch Solemani has have some time to edit the Royal Society Phil Trans A special edition that is now published; Brian Bay, from !LaVision Inc., continued his tour in the UK; the scheme will assist the Drishti volume visualiser author Ajay Limaye, visit in September 2015; two members from the University of Bordeaux, Erwan Plougonven (Dec 2014) and Dominique Bernard (February 2015), visited the UK to exchange experiences on source code integration for quantification visualisation; and Nicola Wadeson updated work for source code to make the Rapiscan RTT x-ray CT Machine usable as an experimental system (Feb-May 2015). Also Daniil Kazantsev has agreed to extend his fellowship until the end of August 2015.
  • EU involvement: There has been exchanges with the EU e-COST programme (EXTREME) with collaborating through workshops and conferences (links through Bill Lionheart, Mark Basham and Daniil Kazantsev). Formal meetings have occurred at the Applied Inverse Problems 2015 conference.
Line: 49 to 49
 
  • CCP-ASEArch collaboration: Starting in April 2014 work, by Evgueni Ovtchinnikov, involves numerical methods, to apply a multigrid solution to improve the issues caused by gradient based regularization coefficients in order to accelerate and stabilise convergence is complete with a a publication submitted (collaboration with Daniil Kazantsev - CCPi Flagship Fellow).
  • The SLA EPSRC funded survey: the results for CCP visualisation user needs has been analysed to consider the long tail of products that the global community uses (>100 responses) and focus our CCPi core development effort on certain products. Launched on 2 February 2015: http://www.vizmatters.cs.manchester.ac.uk/index.php/Main_Page
