Local Hyperthermia with Interstitial Techniques1
The heating of deep visceral tumors with implanted electrodes and with self-regulating ferromagnetic thermoseeds was inves tigated. Clinical trials on six patients heated with implanted electrodes indicate that good local tumor control can be obtained by application of hyperthermia during a normal course of radio therapy. The heating method was found practical, and neither toxicity nor severe p...
متن کاملNew magnetic implant material for interstitial hyperthermia
Magnetic properties and heat generation characteristics of a bio-compatible ceramic Mg1þxFe222xTixO4 system have been investigated as an implant material for the magnetic induction hyperthermia. Curie temperature ðTcÞ of the ceramic decreases with increasing x; and become Tc , 350 K at x 1⁄4 0:35 and ,315 K at x 1⁄4 0:38; which is suitable Curie temperature for implant material. The temperature...
متن کاملInterstitial laser hyperthermia: a new approach to local destruction of tumours.
The use of local hyperthermia to treat cancer of the internal organs has been limited by the difficulty of controlling delivery of heat and limiting the effects to the tumour, but this can be overcome by using laser light transmitted through thin flexible fibres. Laser energy was delivered to tumours through fibres inserted percutaneously through needles directly into the centre of the tumour a...
متن کاملStudy on Interstitial Microwave Hyperthermia with Multi-slot Coaxial Antenna
This study focuses attention on interstitial microwave hyperthermia, which is a popular medical procedure for treatment of pathological human tissues containing tumors. In the paper, the 2D finite element analysis is used to compare the models of the coaxial antenna with one, two and three air slots. The implemented models are based on the wave equation in the TM mode coupled with the Pennes eq...
متن کاملBiodegradable magnesium nanoparticle-enhanced laser hyperthermia therapy
BACKGROUND Recently, nanoparticles have been demonstrated to have tremendous merit in terms of improving the treatment specificity and thermal ablation effect on tumors. However, the potential toxicity and long-term side effects caused by the introduced nanoparticles and by expelling them out of the body following surgery remain a significant challenge. Here, we propose for the first time to di...
