Antenna Design, Radiobiological Modelling, and Non-invasive Monitoring for Microwave Hyperthermia
Licentiatavhandling, 2022
Despite the vast amount of effort invested in HTP and the progress made in this regard during recent years, the clinical exploitation of HT is still hampered by technical limitations and patients can still experience discomfort during clinical trials. This, therefore, calls for a more efficient hardware design, better control of EM power deposition to minimize unwanted hotspots, and more accurate quantification and monitoring of the treatment outcome. Given these demands, the present report tries to address some of the above-mentioned challenges by proposing
- A new antenna model customized for HT applications that surpasses previously proposed models from several points of view.
- A hybrid beamforming method for faster convergence and a versatile, robust thermal solver for handling sophisticated scenarios.
- A radiobiological model to quantify the outcome of a combined treatment modality of the Gamma Knife radiosurgery and HT.
- A differential image reconstruction method to assess the feasibility of using the same system for both heating and microwave thermometry.
