1. Three-dimensional assessment of cardiac function; When right is wrong
Sammanfattning : Assessment of the right side of the heart is important in patients with heart disease; especially in patient with elevated pressure in the lung circulation. Decreased right ventricular function and elevated pressure in the right atrium are of poor prognostic value. LÄS MER
2. Physical Modeling of Brain and Head Kinematics
Sammanfattning : The development of head injury criteria and countermeasures for head protection requires understanding of how different factors affect brain and head kinematics. In this thesis, 2D physical models of the human head were developed and used to evaluate how various factors affect brain kinematics during angular head kinematics. LÄS MER
3. Influence of intracranial features on brain kinematics during head impact : biomechanical aspects concerning teleological protection of the brain
Sammanfattning : .... LÄS MER
4. Pathogenesis of infections related to foreign devices within the cerebral ventricles
Sammanfattning : Coagulase-negative staphyloccoci (CoNS) are the most frequently isolated micro-organisms from infected cerebrospinal fluid (CSF) shunts and temporary ventricular drainage catheters, used in modern neurosurgery. CoNS originate from the skinflora of the patient or the surgeon and gain access to the surface of the implant at the insertion, but the infection can erupt up to a year later or more. LÄS MER
5. Physiological aspects on intracardiac blood flow
Sammanfattning : Magnetic resonance imaging enables detailed in vivo study of complex flow through 3D, time-resolved phase contrast imaging (4D flow). 4D flow may reveal previously unknown aspects of the physiology of intracardiac blood flow, and possibly elucidate pathophysiological processes that have yet to manifest themselves outside the heart.
