  1. 1. Optimizing microwave hyperthermia antenna systems

    Author : Pegah Takook; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; head and neck tumors.; wideband antenna; microwave hyperthermia; time reversal;

    Abstract : 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. READ MORE

  3. 3. Enhancing Tropospheric Humidity Data Records from Satellite Microwave and Radiosonde Sensors

    Author : Isaac Moradi; Chalmers University of Technology; []
    Keywords : CDR; climate; microwave; radiosonde; water vapor; remote sensing; antenna; homogenization; humidity; meteorology; troposphere; radio-frequency;

    Abstract : Water vapor is the most dominant greenhouse gas and plays a critical role in the climate by regulating the Earth's radiation budget and hydrological cycle. A comprehensive dataset is required to describe the temporal and spatial distribution of water vapor, evaluate the performance of climate and weather prediction models in terms of simulating tropospheric humidity, and understand the role of water vapor and its feedback in the climate system.

  4. 4. Advances in Microwave Hyperthermia Treatment using Time Reversal

    Author : Hana Dobsicek Trefna; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microwave hyperthermia; time reversal; microwave thermometry; annular phased array; amplifier system; treatment planning;

    Abstract : 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.
