Digital Signal Processing Seminar

Intelligent diagnostic systems in biosignal analysis and medical imaging form the basis of a new era in the practice of medicine facilitating the:

• Standardisation: Diagnoses obtained with similar criteria in different laboratories can be verified.
• Sensitivity: Findings in a particular subject under investigation may be compared with a database of normal values to determine whether abnormality exists or not.
• Specificity: Findings may be compared with databases derived from patients with known diseases, to evaluate whether they fit a specific diagnosis.
• Equivalence: Results from serial examinations on the same patient may be compared to decide whether there is evidence of disease progression or of response to treatment.

In this lecture, research work will be presented focusing in the development of neural network diagnostic systems in the analysis of biosignals and medical images for the assessment of neuromuscular disorders. More specifically, electromyographic (EMG) signal analysis work will be presented on adaptive pattern recognition, efficient training of neural network models, multiresolution analysis, and the development of a multi-feature / multi-classifier diagnostic system. Furthermore, in medical imaging work will be presented on the analysis of light microscopy muscle biopsy images. Emphasis is given in the development of computationally efficient systems, implemented in real time.

Dr. Constantinos S. Pattichis was born in Nicosia, Cyprus on June 30, 1959. He received the B.Sc. degree in Electrical Engineering from the University of New Brunswick, Canada in 1983, the M.Sc. degree in Biomedical Engineering from the University of Texas at Austin, USA, in 1984, the M.Sc. degree in Neurophysiology from the University of Newcastle upon Tyne, UK, in 1988, and the Ph.D. in Electronic Engineering from the University of London, UK, in 1992. During 1985-1992 he was also working with the Cyprus Institute of Neurology and Genetics where he is now a Visiting Senior Scientist. He is currently an Assistant Professor with the Department of Computer Science at the University of Cyprus. He was the recipient of the 1994 European Community "Marie-Curie" fellowship, and is actively participating in a number of European projects related to Health Telematics. His current research interests include medical imaging, biosignal analysis, artificial neural networks and genetic algorithms. He has published over 40 refereed journal and conference papers in these areas. Dr. Pattichis has been involved in numerous professional society activities, including: President of the Cyprus Association of Medical Physics and Biomedical Engineering, 1996-98; President of the IEEE Cyprus Section, 1998-99; General Co-Chairman, Medical and Biological Engineering and Computing Conference 98 (Medicon'98).
