Imagerie Tridimensionnelle Morphologique et Fonctionnelle en Multimodalité

Abstract : This manuscript is devoted to the display and the analysis of the three-dimensional morphological image data, to the fusion of information provided by a same imaging device but acquired at different times, and to the matching between functional signals and anatomical descriptions.
The first chapter reviews the literature dealing with the acquisition and the modeling of 3D primitives in medical imaging. Several techniques available for the representation of primitives and multivariate functions are reported on the second chapter.
A new conceptual framework, so called "Multifunction Ray Tracing", for 3D medical image rendering and analysis is then proposed. It integrates, in a general scheme, operations such as interpolation, filtering and detection while preserving the overall image functionalities (dissection, manipulation). A solution to speed up the 3D image computation based on frame coherence is also described.
The temporal following of diseases or therapy requires the confrontation of images issued from different examinations. The fourth chapter concerns the 3D registration of the same object sampled in a different coordinate system. The rotation estimation is performed by means of a quaternion formulation.
The last part deals with the projection of functional signals as observed in Electroencephalo-graphy and Magnetoencephalography onto morphological representations of the cerebral space.
