11. Novel Approaches for Application of Principal Component Analysis on Dynamic PET Images for Improvement of Image Quality and Clinical Diagnosis
Sammanfattning : Positron Emission Tomography, PET, can be used for dynamic studies in humans. In such studies a selected part of the body, often the whole brain, is imaged repeatedly after administration of a radiolabelled tracer. LÄS MER
12. On the use of computed tomography in cardiac imaging
Sammanfattning : BackgroundCardiac Computed Tomography Angiography (CCTA) is becoming increasingly useful in the work‐up of coronary artery disease (CAD). Several potential methods for increasing the diagnostic yield of cardiac CT are available. LÄS MER
13. Reeling in private governance approaches for sustainable fisheries : A study of Fishery Improvement Projects
Sammanfattning : In response to the global fisheries crisis new governance models have been developed. In this thesis, I study one such model, Fishery Improvement Projects (FIPs), that have increased in numbers and importance globally, yet received little scientific attention. LÄS MER
14. Positioning Biopsy Needles in the Prostate Gland Using 3D Computer Modelling
Sammanfattning : In the world of medicine, image diagnostics have, until recently, been based merely on two dimensional information sources. The understanding of three dimensional structures has been limited to creating mental images in the mind of the physician, to wax models and to autopsy. LÄS MER
15. Identification of single motor units in ultrafast ultrasound image sequences of voluntary skeletal muscle contractions
Sammanfattning : The central nervous system controls human force production by successive recruitment of motor units in the skeletal muscles and changing their neural firing rate. The motor unit comprises a motoneuron, its innervated muscle fibers, and its axons. LÄS MER
