1. Non-invasive biomedical analysis : recent advances, challenges, and future perspectives
Sammanfattning : Non-invasive healthcare technologies are increasingly pivotal in research anddevelopment due to their affordability and the convenience they offer to bothhealthcare recipients and providers. Alongside traditional non-invasive methodssuch as ultrasound imaging, a variety of innovative non-invasive devices havebeen developed. LÄS MER
2. Non-invasive imaging for improved cardiovascular diagnostics : Shear wave elastography, relative pressure estimation, and tomographic reconstruction
Sammanfattning : Throughout the last century, medical imaging has come to revolutionise the way we diagnose disease, and is today an indispensable part of virtually any clinical practice. In cardiovascular care imaging is extensively utilised, and the development of novel techniques promises refined diagnostic abilities: ultrasound elastography allows for constitutive tissue assessment, 4D flow magnetic resonance imaging (MRI) enables full-field flow mapping, and micro-Computed Tomography (CT) permits high-resolution imaging at pre-clinical level.

3. Computerised Microtomography : Non-invasive imaging and analysis of biological samples, with special reference to monitoring development of osteoporosis in small animals
Sammanfattning : The use of Computerised microtomography (CμT) in biomedical research is well established, with most applications developed at synchrotron facilities. The possibility to non-invasively monitor morphological changes in biological samples, makes it an attractive technique in biomedicine. LÄS MER
4. Microwave Transistor Noise Model Extraction Methods and a Non-Contacting Scattering Parameter Measurement Method
Sammanfattning : This thesis has two parts. The first part discuss noise model extraction methods for FETs. The second part describe theory and implementation of a non-contacting S-parameter measurement method. Noise is an important aspect for a circuit designer, because noise generated in the circuit is a sensitivity limiting factor. LÄS MER
5. Unstable coronary artery disease : non-invasive indicators of severity of coronary lesions and the effects of thrombolysis
Sammanfattning : Non-invasive indicators of severity of coronary lesions and the effects of thrombolysis were evaluated in 205 men, 38 to 70 years of age with unstable coronary aticty disease (CAD)- i.e. unstable angina or non-Q wave myocardial infarction - admitted to the coronary care units in nine hospitals.
