Future trends in medical applications of microwave technique and technology can be seen in development of new diagnostic and imaging methods based on high frequency EM field. A significant importance for the future can be identified for the following methods: Microwave tomography, Microwave radiometry, Measurement of complex permittivity, Imaging in the Terahertz waves band and Microwave diagnostic...
In this paper is presented our longstanding experience with combination of teleradiotherapy and superficial hyperthermia in the treatment of patients with head and neck cancers, especially in cases with superficial tumors or lymph node metastases, in the Institute of Radiation Oncology in Prague. Microwave thermotherapy - hyperthermia in combination with other treatment methods (mainly with teleradiotherapy)...
Medical applications of microwaves (i.e. a possibility to use microwave energy and/or microwave technique and technology for therapeutical purposes) are a quite new and a very rapidly developing field. Microwave thermotherapy is being used in medicine for the cancer treatment and treatment of some other diseases since early eighties. In this contribution we would like to offer general overview of...
The measurement of dielectric parameters of wet textile materials is very important for the design of microwave drying and heating applicators in textile industry. In this contribution there are presented results of two measurement systems - Six-port measurement system and Agilent Impedance/material analyzer. Dielectric properties generally depend on the frequency of applied electromagnetic field,...
Paper deals with the complex permittivity measurement of biological tissues. Application of a waveguide probe for this measurement is shown. A non-destructive and non-invasive method based on reflection coefficient measurement attaching the material under test is used. New types of the probes are under investigation - the section of waveguide with H cross-section, the section of waveguide with the...
The main aim of this work is to design and to simulate an exposure chamber which can simulate mobile phone emission patterns in order to analyze the influence of electromagnetic field on small animals. During our previous research we found the most suitable type of an exposure chamber for this purpose. The basic properties such as electromagnetic field distribution and impedance matching of our designed...
Microwave thermotherapy is being used in medicine for the cancer treatment and treatment of some other diseases since early eighties [1,2,3,4]. Until now in temperature monitoring and control there is a lack of non-invasive 3D thermometry system, e. g. either Nuclear Magnetic Resonance (NMR) or ultrasound (US). The goal of this paper is to describe design and experimental evaluation of a new type...
