1. Design and Performance of Some Components for a Millimeter Wave Imaging Receiver
Sammanfattning : This thesis deals with the design and performance of some novel devices for an imaging receiver, operating in the frequency band centered at 100 GHz, to be used in radio astronomy research. The emphasis is given on simple, small and reliable devices in order to reduce the complexity of an already complex receiver. LÄS MER
2. Imaging in Idiopathic Normal Pressure Hydrocephalus : The value of structured radiological evaluation
Sammanfattning : Background: Idiopathic normal pressure hydrocephalus (iNPH) is a neurological condition where the symptoms include disturbed gait, balance, cognition and continence. The diagnostic guidelines are based on typical symptoms combined with imaging showing enlarged ventricles. LÄS MER

4. Aortic valve imaging - Towards new standards in prosthetic valve endocarditis
Sammanfattning : Background: Aortic prosthetic valve endocarditis (PVE) is a disease with high mortality, and diagnosis is difficult. Transesophageal echocardiography (TEE) has been the mainstay imaging modality in the diagnostic workup, but TEE has diagnostic shortcomings. Thus, new imaging methods might improve the diagnostic workup of PVE. LÄS MER
5. Millimeter-Wave Impulse Radio
Sammanfattning : This thesis investigates the opportunity of wireless multi-gigabit per second communication at the millimeter-wave (mmW) frequencies around 60 GHz by using impulse radio and nanoelectronics. Today most wireless communication take place in the microwave region, where several different systems and applications are crowding the narrow-band channels. LÄS MER
