1. Keeping track of time : Daily time management, participation, and time-related interventions for children, adolescents, and young adults with neurodevelopmental disorders
Sammanfattning : The overall aim of this thesis was to investigate daily time management (DTM) and time-related interventions aiming to enhance participation in everyday activities among school-age children and young adults with neurodevelopmental disorders.In study I, experiences of participation when using time assistive devices (TADs) in daily activities were investigated from the perspective of young adults (aged 17–37) with intellectual disabilities (ID) (n = 9), using semi structured interviews.

2. X-ray and neutron μCT of biomedical samples: from image acquisition to quantification
Sammanfattning : Even though the validity of x-ray computed tomography in the analysis of biomedical samples is nowadays undisputed, the more recent imaging techniques and more advanced instruments (such as synchrotrons) are still relatively unknown to many medical doctors that could benefit from them.The doctoral work presented in this thesis joins a collective effort from the imaging community to demonstrate potential applications of advanced x-ray and neutron imaging methods to preclinical medical research, with the hope of contributing to reach a “critical mass” in the medical community and in the public opinion as well.

3. Image Processing for Quantitative Scintillation-Camera Imaging. Application to Radionuclide Therapy
Sammanfattning : Individual-based determinations of the absorbed dose in radionuclide therapy largely rely on absolute measurement of the activity distribution and its redistribution over time. Scintillation-camera imaging is the most commonly employed measuring technique, applied in planar or SPECT mode, sometimes in combination with structural images from CT. LÄS MER
4. Automatic segmentation in CMR - Development and validation of algorithms for left ventricular function, myocardium at risk and myocardial infarction
Sammanfattning : In this thesis four new algorithms are presented for automatic segmentation in cardiovascular magnetic resonance (CMR); automatic segmentation of the left ventricle, myocardial infarction, and myocardium at risk in two different image types. All four algorithms were implemented in freely available software for image analysis and were validated against reference delineations with a low bias and high regional agreement. LÄS MER
5. High resolution laboratory x-ray tomography for biomedical research : From design to application
Sammanfattning : Laboratory x-ray micro- and nano-tomography are emerging techniques in biomedical research. Through the use of phase-contrast, sufficient contrast can be achieved in soft tissue to support medical studies. LÄS MER
