The use of hyperthermia as anti-cancer treatment in combination with other therapies assumes every day a growing interest. In this paper the main characteristics of a microwave system and an applicator for hyperthermia treatment of small in-vivo melanoma tumours are described. The results of temperature measurements on mice, show the possibility to design a protocol for hyperthermia treatment of small...
Nowadays microwave thermotherapy belongs to methods of treatment for cancer diseases. This method is often used in combination with classical therapies, which brings more success during treatment of tumors. The area is heated by microwave energy through microwave applicator. This paper deals with design, modelling and testing of planar spiral type of applicator for local microwave thermotherapy.
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)...
The use of electromagnetic fields in biomedicine for cancer treatment and diagnostics, nowadays begin to be quite widespread. This paper describes the design and the evaluation of a microwave applicator for treatment of small subcutaneous tumours implanted on animal model. The support of computer simulations was used to evaluate and optimise the fundamental parameters of the applicator and the SAR...
Microwave hyperthermia is a promising method of cancer treatment used to increase the temperature within the interval of 40 - 44degC. The goal of this paper is to introduce the possibility of treatment planning for superficial hyperthermia using COMSOL Multiphysics. The real model of the patient with recurrent breast cancer was developed. The waveguide horn applicator with aperture of 10 x 10 cm was...
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 object of this work is to design a microwave applicator for local thermotherapy, which is work on the principle of a slot line. The working frequency of this applicator is 434 MHz. A 3D simulator of electromagnetic field is used for numeric simulation and consequential optimalization. After that, the designed applicator is made and its reflectance and specific absorption rate is measured in phantom...
Research about interactions between EM Field and biological tissues for cancer treatment assumes every day a growing interest. In this paper we will describe the main characteristics of a microwave system developed for hyperthermic treatment and biological experiments. We will consider also some experiments on agar phantom reproducing a tumour bearing mouse, performed for a preliminary evaluation...
The possibility to use shorted circular micros trip antenna as an applicator for local hyperthermia is described in this paper. This applicator is designed to provide a local treatment on areas located on the body surface or in its proximity. The applicator is designed by aid of 3D electromagnetic field simulator SEMCAD X light at working frequency of 434 MHz. Results of impedance matching measurement...
Nowadays hyperthermia is one of the possible cancer treatment method used in combination with classical therapies in several countries in the world. In this article we described the designed and optimization of a microstrip type applicator for the treatment of superficial diseases. The optimization was made in order to obtain a more uniform SAR distribution, which is one of the requirements to achieve...
Microwave thermotherapy is being used for cancer treatment. The treatment area is heated by microwave energy, which irradiated from microwave applicator. As an applicator we can use the waveguides and their possible modifications. This paper describes simulated and measured thermal distributions of the lucite cone applicator, which is composed from feeding waveguide and strip line horn (lateral faces...
