1. Spectral Computed Tomography with a Photon-Counting Silicon-Strip Detector
Abstract : 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. READ MORE

2. Spectral image quality and applications in breast tomosynthesis
Abstract : In the 1970s, it was determined that screening mammography is an efficient tool in fighting the increasing number of women dying from breast cancer, and many countries have established screening programs since then. Mammography systems have improved substantially over the years with one of the major advances being the transition from x-ray film to digital x-ray detectors. READ MORE

4. Decision making in emergency management
Abstract : The thesis is based on two studies conducted on behalf of the Swedish Emergency Services Agency. One study focused on the problems associated with selection and training of future emergency directors in Sweden. The other study surveyed the emergency directors’ needs for decision support systems in major accidents. READ MORE
