ROYAL STATISTICAL SOCIETY MEDICAL SECTION MEETING ON IMAGING Tuesday 26 April 2005 4.00 - 6.00 (tea at 3.30). To be held at the RSS, 12 Errol Street, London EC1Y 8LX (directions http://www.rss.org.uk/about/direction.html) Pre-registration is recommended - to register email: [log in to unmask] or tel. 020 7638 8998 "How to segment 3-D images and analyse 1-D electrophoresis gels" Chris Glasbey, Biomathematics and Statistics Scotland Abstract Dynamic Programming (DP) is a fast, elegant method for finding the global solution to some optimisation problems, including segmenting 2-D images and aligning pairs of tracks in electrophoresis gels. Extensions will be considered, where DP is not directly applicable, illustrated by 3-D X-ray computed tomography and pulsed field gel electrophoresis. "Surface shape analysis from MR images, with an application to measuring cortical surface asymmetry in schizophrenia" Ian Dryden, University of Nottingham Abstract We introduce some methods for the statistical shape analysis of surface data, with an application in neuroscience. An initial key step in comparing the brains is to co-register the MR scans, and we consider maximum likelihood and Bayesian procedures. Size and shape analysis of the registered cortical surfaces is then carried out, focussing on differences in torque and on overall size and shape. ______________________________________ Janet Peacock School of Health Sciences and Social Care Brunel University Borough Road, Isleworth, TW7 5DU.
