1. 1. Unsupervised Segmentation of Head Tissues from Multi-Modal Magnetic Resonance Images: With Application to EEG Source Localization and Stroke Detection

   Författare :Mahmood Qaiser; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stroke; EEG source localization; Image segmentation; reconstruction; magnetic resonance; brain;

   Sammanfattning : The automated segmentation or labeling of individual tissues in magnetic resonance (MR) images of the human head is an essential first step in several biomedical applications. The resulting segmentation yields a patient-specific labeling of individual tissues that can be used to quantitatively characterize these tissues (e.g. LÄS MER

3. 2. Automated Patient-Specific Multi-tissue Segmentation of MR Images of the Head

   Författare :Mahmood Qaiser; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D image segmentation; mean shift; Bayesian; Magnetic resonance; brain or head tissues; source localization.;

   Sammanfattning : The automated segmentation of magnetic resonance (MR) images of the human head is an active area of research in the field of neuroimaging. The resulting segmentation yields a patient-specific labeling of individual tissues and makes possible quantitative characterization of these tissues (e.g. LÄS MER

4. 3. Generation of Patient Specific Finite Element Head Models

   Författare :Johnson Ho; Svein Kleiven; Michael Gilchrist; KTH; []
   Nyckelord :Injury Prevention; Patient Specific; Finite Element Head Model; Anatomical Structures; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Traumatic brain injury (TBI) is a great burden for the society worldwide and the statisticsindicates a relative constant total annual rate of TBI. It seems that the present preventativestrategies are not sufficient. To be able to develop head safety measures against accidents ine.g. LÄS MER

5. 4. A Finite Element Model of the Human Head for Simulation of Bone-conducted Sound

   Författare :You Chang; Stefan Stenfelt; Namkeun Kim; Frank Böhnke; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone conduction; finite element model，bone-conduction devices;

   Sammanfattning : Bone conduction is usually understood as the hearing sensation based on the vibrations of the skull bone and surrounding tissues. The fact that vibration of the skull bones can result in a sound percept has been known for a long time. However, it is difficult to give a general definition of BC sound. LÄS MER

7. 5. Interrogation of drug effects on the lipid composition of single cells and Drosophila brain using ToF-SIMS imaging

   Författare :Thuy Mai Hoang Philipsen; Chalmers tekniska högskola; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Drosophila melanogaster; Keywords: Mass spectrometry imaging; PC12 cell.; ToF-SIMS; zinc deficiency; lipid change; methylphenidate; cocaine; cognition; omega-3 and 6- fatty acids;

   Sammanfattning : Lipids are essential for all living organisms on Earth. The most important function of lipids is that they act as the building blocks of cellular membranes. Lipids consist of polar head groups and non-polar tail groups and assemble into bilayer structures to create cell and organelle membranes. LÄS MER
