About the project
This project will study hardware-based approaches to control X-ray scatter in high energy XCT systems assemblies using a novel beamstop array design to estimate the scattered signal.
High energy X-ray tomographic imaging is a crucial technology for the inspection of various high value assets. Unfortunately, by increasing X-ray energies to the required levels to penetrate metal components of the required dimension, the dominant physical interactions between X-rays and matter shifts into a regime where X-ray scattering becomes a dominant factor. This scattered radiation currently can significantly degrade tomographic image quality thus masking component defects.
This project will investigate the reduction and removal of the scatter signal from X-ray tomographic data acquired with high energy X-ray sources suing hardware-based approaches. This will require a careful choice of beamstop material, advanced geometric design and a careful choice of suitable manufacturing processes.
You will work alongside the team at the University of Southampton’s µ-VIS facility, a dedicated X-ray Computed Tomography (XCT) centre. The centre is part of the UK’s National Facility for lab-based XCT and houses some of the UK’s largest micro-focus CT scanning systems, capable of unveiling sub-surface information from materials, components and structures. With strong links between both research and industry, the centre itself is used for aircraft crash investigations, Formula 1, space technology and much more.
The Centre for Doctoral Training in Complex Integrated Systems for Defence & Security (CISDnS) is committed to promoting equality, diversity and inclusivity. We welcome all applicants regardless of their gender, ethnicity, disability, sexual orientation or age, and will give full consideration to applicants seeking flexible working patterns and those who have taken a career break or are transitioning into a new role. The University has a generous maternity policy, onsite childcare facilities, and offers a range of benefits to help ensure employees’ well-being and work-life balance.
