  1. 6. 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.

  3. 7. 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.

  7. 10. Towards a microwave hyperthermia system for head and neck tumors

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

    Sammanfattning : Hyperthermia has shown the ability to enhance the performance of radiotherapyand chemotherapy in many clinical trials. The incidence of increased tissue toxicityas a result of high radiotherapy dose, made hyperthermia as a safe methodin combination with radiotherapy to enhance the treatment outcome. LÄS MER
