1. 1. Optimizing microwave hyperthermia antenna systems

   Författare :Pegah Takook; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; head and neck tumors.; wideband antenna; microwave hyperthermia; time reversal;

   Sammanfattning : This thesis presents design and optimization of a microwave hyperthermia antenna system for treatment of head and neck cancer as well as brain cancer. Hyperthermia has shown the ability to enhance the performance of radiotherapy and chemotherapy in many clinical trials. LÄS MER

3. 2. Advances in Microwave Hyperthermia Treatment using Time Reversal

   Författare :Hana Dobsicek Trefna; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microwave hyperthermia; time reversal; microwave thermometry; annular phased array; amplifier system; treatment planning;

   Sammanfattning : The last twenty years have seen many clinical studies showing the ability of hyperthermia to remarkably enhance response to radiation therapy and chemotherapy. The objective of hyperthermia treatment is to raise the temperature in tumors to therapeutic levels, for a sufficient period of time, in order to achieve cell death or render the cells more sensitive to ionizing radiation and/or chemotherapy.

4. 3. Antenna Design, Radiobiological Modelling, and Non-invasive Monitoring for Microwave Hyperthermia

   Författare :Morteza Ghaderi Aram; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UWB Antennas; Bio-Electromagnetics; Hyperthermia; Microwave Thermometry; Radiobiological Modeling;

   Sammanfattning : The death toll of cancers is on the rise worldwide and surviving patients suffer significant side effects from conventional therapies. To reduce the level of toxicity in patients treated with the conventional treatment modalities, hyperthermia (HT) has been investigated as an adjuvant modality and shown to be a potent tumor cell sensitizer for radio- and chemotherapy.

5. 4. Towards UWB microwave hyperthermia for brain cancer treatment

   Författare :Massimiliano Zanoli; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; treatment planning; microwave hyperthermia; brain cancer;

   Sammanfattning : Despite numerous clinical trials demonstrating that microwave hyperthermia is a powerful adjuvant modality in the treatment of cancers, there have been few instances where this method has been applied to brain tumors. The reason is a combination of anatomical and physiological factors in this site that require an extra degree of accuracy and control in the thermal dose delivery which current systems are not able to provide.
