The work covered in this thesis deals with the problem of automatically
registering 3D images acquired from different medical imaging modalities.
The approach taken is to develop generic measures of image registration derived
from the co-occurence of values in the two images. The development
of statistical alignment measures is reviewed. The registration problem is
then expressed in terms of entropy and developed using tools from information
theory. The problem of the optimization of the registration process in
the different types of algorithms is identified as important and the power of
Genetic Algorithms is applied.
The application of image registration techniques, implemented during this
thesis, in complex situations is evaluated. The cases of patients with brain
ischemia and brain tumour residual disease are elaborated. This is accomplished
with the formation of Groupwares where the tacit knowledge, owned
by the individual specialists that take part in the collaboration, is exposed
and made explicit in the process of the evaluation of the findings, provided
by the fused images. This is performed in a high performance computer network
that has been developed between the Department of Medicine and the
University Hospital. / Η παρούσα εργασία ασχολείται με το πρόβλημα της αυτοματοποιημένης προσαρμογής και σύντηξης τρισδιάστατων απεικονίσεων από διαφορετικές ιατρικές απεικονιστικές μεθοδολογίες.
