6. Evaluation of absorbed dose and image quality in mammography
Abstract : Mammography refers to the X-ray examination of the human breast, and is considered the single most important diagnostic tool in the early detection of breast cancer, which is by far the most common cancer among women. There is good evidence from clinical trials, that mammographic screening can reduce the breast cancer mortality with about 30%. READ MORE

7. The balancing act of living with symptoms. Patient-reported data and quality of care during and after treatment with proton beam therapy in patients with brain tumors
Abstract : is thesis focuses on patients with primary brain tumors undergoing proton beam therapy (PBT) and the consequences of the treatment. Quality of care (QoC) in a recently established clinic in Sweden was also evaluated. READ MORE

8. Osteocytes as indicators of bone quality - multiscale structure-composition characterisation of the bone-implant interface
Abstract : By virtue of certain design features, bone anchored metal implants can be made to elicit a strong initial osteogenic response, i.e., the amount of bone formed. READ MORE

9. The microdosimetric variance-covariance method used for beam quality characterization in radiation protection and radiation therapy
Abstract : Radiation quality is described by the RBE (relative biological effectiveness) that varies with the ionizing ability of the radiation. Microdosimetric quantities describe distributions of energy imparted to small volumes and can be related to RBE. READ MORE

10. Applications of Ion Beam Methods in Silicide/Si and Silicide/GaAs Nanometre Structures
Abstract : Ion beam methods are used to analyse material (Ion Beam Analysis, IBA) and to modify the target (Ion Beam Modification of Materials, IBMM). In this thesis, ion beams have been used in various IBA techniques to investigate the surface nanometre structures, and also in an ion beam synthesis (IBS) technique to form thin films and to modify material properties.
