1. Spectral Computed Tomography with a Photon-Counting Silicon-Strip Detector
Sammanfattning : Computed tomography (CT) is a widely used medical imaging modality. By rotating an x-ray tube and an x-ray detector around the patient, a CT scanner is able to measure the x-ray transmission from all directions and form an image of the patient’s interior. LÄS MER
2. Aspects of Fluorescence diagnostics and photodynamic therapy of non-melanoma skin cancer
Sammanfattning : Aspects of fluorescence diagnostics and photodynamic therapy in non-melanoma skin cancer. Carin Sandberg Department of Dermatology and Venereology, Institute of Clinical Sciences at Sahlgrenska Academy, University of Gothenburg, Gothenburg, Sweden. LÄS MER
3. Simulation of consolidation processes by eulerian two-fluid models
Sammanfattning : The objective of this report is to study a model of agravity and shear induced consolidation process of a dense,flocculated suspension.The suspension is modeled as a two-constituent mixture of afluid and solid particles by an Eulerian two-phase fluid model. LÄS MER
4. New Efficient Detector for Radiation Therapy Imaging using Gas Electron Multipliers
Sammanfattning : Currently film is being replaced by electronic detectors for portal imaging in radiation therapy. This development offers obvious advantages such as on-line quality assurance and digital images that can easily be accessed, processed and communicated. LÄS MER
5. Novel Technologies for Mode-Locking of Solid-State Lasers
Sammanfattning : The subject of this thesis is the investigation of novel technologies for mode-locking of diode-pumped, solid-state lasers. Novel saturable absorbers are used: quantum dots (QDs) and carbon nanotubes (CNTs), which both are low-dimensional nano-formations. In addition, mode-locking by cascaded nonlinearities is explored.
