2020 Dimensional X-ray Computed Tomography Week: 29 June - 2 July

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 its 5th year the event is being hosted by the HMXIF at the University of Manchester; part of the Henry Royce Institute for advanced materials and Registration is now OPEN

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 (http://www.manchesterairport.co.uk).

Hands-on Test Scans

We are making available an Exclusive XCT Service during this conference. A set of XCT imaging machines will be manned and available, as well as experts on post-processing and analysis of the data sets. If you would like to scan a particular sample and/or be present during a master-class demonstration then please register.

Email Tristan Lowe Tristan.Lowe@manchester.ac.uk to book specific one hour slots.


On the previous two days there are various training events. The first training day will focus on practical XCT metrology for calibrating systems that users should be able to apply to their own laboratory instruments. The second training day will focus on producing analysis recipes in Avizo for inline processing of data directly from an instrument (industry 4.0 type approach) or large data volumes such as those from a synchrotron. The second day will also look at integrating calibration methods into the analysis of XCT data.

Training Day 1, 29 June 2020: case studies and exemplars
a. voxel size assessment using examples of commercial software and python (Tristan)
b. Software tools for industrial applications i.e. CAD comparisons (Peter)
c. construction of automated analysis recipes for industrial applications (Peter/Tristan)
d. building in uncertainty from instrument measurements into data analysis (Tristan/Peter)

Training Day 2, 30 June 2020:
a. Introduction to metrology, ra. elated 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 (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
