2. Spectral Photon-Counting Computed Tomography with Silicon Detectors: New Models and Applications
Sammanfattning : X-ray computed tomography (CT) is a widely used imaging modality that enables visualization of nearly every part of the human body. It is used for diagnosis of disease and injury as well as medical treatment planning. LÄS MER
3. Characterization and Optimization of Silicon-strip Detectors for Mammography and Computed Tomography
Sammanfattning : The goal in medical x-ray imaging is to obtain the image quality requiredfor a given detection task, while ensuring that the patient dose is kept as lowas reasonably achievable. The two most common strategies for dose reductionare: optimizing incident x-ray beams and utilizing energy informationof transmitted beams with new detector techniques (spectral imaging). LÄS MER
4. Measurements of the Standard Model Higgs boson cross sections in the WW* decay mode with the ATLAS experiment
Sammanfattning : This thesis summarises measurements of the Standard Model Higgs boson production cross sections based on proton–proton collision data at √s = 13 TeV produced by the Large Hadron Collider at CERN. By analysing data collected during 2015 and 2016 by the ATLAS experiment, corresponding to an integrated luminosity of 36 fb−1, the Higgs boson gluon–gluon fusion and vector boson fusion production cross sections are measured in the WW* decay mode.

5. Towards nanodosimetry: therapeutic radiation measurements using the variance method
Sammanfattning : Understanding how radiation damage occurs in human tissue seems to lie in the knowledge of energy depositions in DNA-size volumes, with diameters typically around a few nanometres. In such small volumes the energy transfers are stochastic and described using distributions of events along a particle track and relevant mean values. LÄS MER
