2 INLEIDING doelgroep Driedimensionele beeldvorming heeft een ingrijpende invloed op de geneeskundige praktijk. Met de introductie van de conebeamtechnologie werd 3D-diagnostiek ook ingevoerd in de dagelijkse tandheelkundige praktijk. Bewust is gekozen voor een doelgroep van studenten biomedische wetenschappen, wiskunde, fysica, geneeskunde maar ook artsen, tandartsen en geneesheren-specialisten medische beeldvorming zullen hun gading vinden. Naast het gekende diagnostische vermogen worden steeds meer behandelingsplannen gebaseerd op de 3D-datasets in daartoe geëigende softwarepakketten. Hierbij kunnen ingrepen op het beeldscherm gesimuleerd worden, kunnen chirurgische hulpmiddelen op maat van de patiënt vervaardigd worden of kan beeldvorming de basis vormen voor navigatiechirurgie. Voor iedere module kan afzonderlijk ingeschreven worden. De lezingen worden in het Engels gegeven. dagindeling Typisch is dat de informatie van de detectoren omgezet wordt tot een beeld via een reeks wiskundige bewerkingen. Hoewel clinici vooral geïnteresseerd zijn in het driedimensionele beeld en de daarbij horende diagnostiek en therapie, kan de volle diepgang van de gewonnen informatie slechts naar waarde ingeschat worden als men het ontstaanstraject van het tot stand gekomen beeld begrijpt. Hier hebben we de inbreng van ingenieurs nodig. Deze lezingen pogen hierbij een hulp te zijn. Hoewel de sprekers wereldfaam genieten, proberen ze hun boodschap in eenvoudige heldere taal te brengen voor niet-wiskundigen en voor niet-ingenieurs. Iedere cursusdag heeft éénzelfde structuur: Lezing Lezing Lezing Lezing 4 2 3

Buzug received his Diplom-Physiker degree in 1989 and his Ph.D. in 1993 in Applied Physics both from the Christian-Albrechts-University of Kiel, Germany. In the end of 1994 he joined the Philips Research Laboratories Hamburg, Germany. He was the leader of the Philips Research Cluster Medical Image Processing and responsible for several projects in that field. He has published numerous journal articles, conference papers and books. He is editor of the international Journal of Computing and Information Technology (CIT). He is member of the German Physical Society (DPG), German Society of Biomedical Engineering (DGBMT), German Society of Nondestructive Testing (DGfZP) and the IEEE. In October 1998 he has been appointed as professor of Physics and Medical Engineering at the RheinAhrCampus Remagen he was head of the Academic Development Committee of the RheinAhrCampus Remagen he was head of the Joint Council of Campus Departments and Director of the Institute of X- Ray Optics (IXO) at RheinAhrCampus Remagen. In December 2006 he became Director of the Institute of Medical Engeneering at the University of Luebeck. Topics Computed Tomography: From Photon Statistics to Modern Cone Beam CT The main focus of the book is a detailed derivation of reconstruction algorithms in 2D and modern 3D cone-beam systems. A thorough analysis of artifacts, noise and dose considerations give further insight to current computer tomography systems. The author will cover a number of issues of this book.
