Practical CT Reconstruction
Date: TBC May 2025
Location: CiMAT Labs, University of Warwick, Coventry, CV4 7AL
Cost: £800 for Industry, £400 for academics
Enquiries: Jay Warnett
The reconstruction of projection data to CT image slices is often seen as a black box and best left to manufacturer software. In this course we dispel the myths of difficulty and inaccessibility, providing you with the tools to implement your own reconstruction protocols independent of the system manufacturer: attendees will generate scripts they can immediately implement in their own lab!
Participants will learn how the analytical (Filtered Back Projection/FDK) and iterative reconstruction work through practical exercises with real world data, underpinned by theoretical understanding. Data import, centre of rotation and beam hardening corrections are discussed and implemented. Across the exercises we will experience region of interest artefact corrections, understand the impact of noise and dynamic range, and exploit iterative reconstruction for reduced projections.
Implementing iterative reconstruction is likely new to most, and we will share the benefit of our experience with our lab data. Considerations include which algorithm to use, how many projections is enough data to stopping rules. Following this exposure you too can benefit from much faster acquisitions using limited data!
The course is designed with minimum programming experience required, but attendees must have knowledge in image analysis software (Avizo/Dragonfly/VG/ImageJ on site).
