Benjamin Irving presents work on automated analysis of the airways in CT scans for the modelling of TB at 'The Challenge of TB: UCL's Contribution' held on 24th March 2010. This innovative project, in conjunction with colleagues from Cape Town, SA, is looking to mathematics and physics to develop a screening tool to detect TB based on digital radiography. The process aims to analyse 3D CT images of airways of patients with TB to develop a statistical model of airway deformation that can be used to screen for TB. The 3D findings will later be applied to 2D radiography to develop the screening tool further.
