1. Statistical methods in medical image estimation and sparse signal recovery
Sammanfattning : This thesis presents work on methods for the estimation of computed tomography (CT) images from magnetic resonance (MR) images for a number of diagnostic and therapeutic workflows. The study also demonstrates sparse signal recovery method, which is an intermediate method for magnetic resonance image reconstruction. LÄS MER
2. Contributions to deep learning for imaging in radiotherapy
Sammanfattning : Purpose: The increasing importance of medical imaging in cancer treatment, combined with the growing popularity of deep learning gave relevance to the presented contributions to deep learning solutions with applications in medical imaging.Relevance: The projects aim to improve the efficiency of MRI for automated tasks related to radiotherapy, building on recent advancements in the field of deep learning.

3. Effects of antiresorptive agents on inflammation and bone regeneration in different osseous sites - experimental and clinical studies
Sammanfattning : The biological mechanisms involved in bone regeneration in osteoporotic bone and the effect of antiresorptive drugs in relation to surgically inserted biomaterials are not fully understood. Improved osseointegration of titanium implants but also adverse effects of antiresorptive therapies, such as osteonecrotic jaw have been described in the literature. LÄS MER
4. Evaluation of fucosylated receptors for Cholera toxin in the human small intestine
Sammanfattning : Cholera toxin (CT) produced by Vibrio cholerae is the causative agent for the diarrheal disease cholera. Cholera is yearly afflicting millions and is estimated to kill over 100 000 people every year. In this thesis I aimed to better understand the role of noncanonical CT receptors, e.g. LÄS MER
5. Optimizing computed tomography : quality assurance, radiation dose and contrast media
Sammanfattning : Computed tomography (CT) is an important modality in radiology; it enables imaging of the inside of patients without superimposed anatomy. The radiation dose and quality of a CT image are highly dependent on the CT scanner, the scan settings and, if applicable, the timing and dosage of the intravenous contrast media (CM). LÄS MER
