dXCT conference 2020

This event has been postponed

2020 Dimensional X-ray Computed Tomography Week

The dXCT 2020 conference set to take place in Manchester has been postponed to 2022 due to COVID-19.
This decision has been made by the organising committee in light of the uncertainty caused by COVID-19 and to allow people to focus their attention on managing this ongoing crisis.
The next dXCT conference will be held in 2021 at the National Physical Laboratory, and the conference will return to Manchester in 2022.

Further information on dXCT 2020 may be available on the host’s associated webpage at DimensionalXCT2020

Welcome to The Dimensional X-ray Computed Tomography (dXCT) conference; an annual event, coordinated by the NPL, presenting and disseminating the latest developments in XCT for dimensional measurement and its industrial impact across a variety of applications. The conference defines synergies and opportunities of collaborations between different organisations and commercial representatives.

In it's 5th year it is being hosted at The University of Manchester; Royce Institute and HMXIF.


Main themes

  • New developments in dimensional XCT
  • Metrology for Additive Manufacturing
  • Dimensional CT and Medical/Bio Applications
  • Dimensional CT in Industry including Automotive and Aerospace
  • Challenges of High Density Components
  • Developing Production Ready Workflows
  • Traceability and Verification

Important Dates

  • 1-2 July Main dXCT conference
  • 29-30 June dXCT training sessions
  • 19 of April Abstract submission deadline
  • 26 of April Acceptance of abstracts
  • 24 of June Registration deadline

Venue and Location

The main conference is being held at the Schuster Building, within the University of Manchester which has excellent road, rail and train links. For details of how to get to Manchester, please visit the University 'How to find us' page.

Accommodation options

Delegates will need to organise their own accommodation as the Secretariat are unable to make room reservations on behalf of delegates. List of close options will be posted here.

Overseas visitors

For overseas visitors, the most convenient point of arrival is Manchester International Airport

Local Organisation Committee

  • Tristan Lowe (University of Manchester)
  • Martin Turner (University of Manchester, STFC)
  • Hannah Saunders (Royce Institute University of Manchester)


Registration will open presently

Please consider also registering for information with the CCPi listserv Funds and travel grants are available from the CCPi (especially for students) for networking.

Pre-conference days of training and tutorials focused on 3D dimensional metrology and dimensional metrology with XCT, will be provided and can be booked at an extra cost during registration. Please note that numbers for the training day may be limited and will be allocated on a first-come-first-served basis.

Conference and Social Programme

Full details and session topics of the conference programme will be linked here.

The DXCT Conference isn’t just about technical sessions and we’re preparing an exciting and full social programme.

  • Drinks reception at the NEW Royce Institute Building (should be ready when you arrive ;-)
  • Conference dinner

On the previous two days there are various training events:

Day 1

 a. voxel calibration measurements using Avizo package for data processing (Tristan)

 b. Useful tools for industrial applications i.e CAD comparisons (Peter)

 c. construction of automated analysis recipes (similar to the industrial meeting you attended) for industrial applications (Peter/Tristan)

 d. building in uncertainty from instrument measurements into visualized and analysed data (Tristan/Peter)

Day 2

 a. introduction to metrology, related fields and applications (Stephen/Wenjuan) – 1hr
      - 1D, 2D, 3D
      - Related fields, in industry
      - Applications in the industrial fields

 b. Error sources relating to XCT instruments (Tristan/Stephen)
      - X-ray source stability
      - Detector variability – possibility Nigha Vo
      - Rotational issues – artefacts
      - Fsd errors
      - Image quality

 c. Standard instrument check (Stephen/Wenjuan)
      - this would include demonstrations of alignment, focal spot wobble and beam focus on the instruments 

 d. Voxel size calibration in XCT (Tristan)
      - we can use 3 potential techniques that users can then use directly in  their own labs
      - 2 ruby sphere method
      - grid method
      - multi ceramic ball method
      - analysis would then be demonstrated using Avizo and python

 e. Spatial resolution checks and image quality (Tristan/Stephen/Wenjuan)
      - presentation on the concepts, applications and signal processing
      - 2D jima chart demonstration
      - 3D spatial target

Next Year

The next conference in 2021 will be held at NPL.

Date: Monday, 29 June, 2020 - 10:00 to Thursday, 2 July, 2020 - 16:00
