2. 1. Segmentation and Visualisation of Human Brain Structures

   Author : Roger Hult; Ewert Bengtsson; Lennart Thurfjell; Håkan Hall; Ingrid Agartz; Arvid Lundervold; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; segmentation; visualisation; brain; cortex; hippocampus; autoradiography; MRI; PET; ROI; Bildanalys; Image analysis; Bildanalys; Computerized Image Analysis; datoriserad bildanalys;

   Abstract : In this thesis the focus is mainly on the development of segmentation techniques for human brain structures and of the visualisation of such structures. The images of the brain are both anatomical images (magnet resonance imaging (MRI) and autoradigraphy) and functional images that show blood flow (functional magnetic imaging (fMRI), positron emission tomography (PET), and single photon emission tomograpy (SPECT)).
