124. Soft-Heating Method of ferromagnetic amorphous particle for interstitial hyperthermia

Low Invasive Temperature Monitoring Method for Hyperthermia Using Induction Heating

In this study, we develop a local heating method and monitoring method for hyperthermia using the Ferromagnetic Implant with Low Curie Temperature (FILCT) under a high frequency magnetic field. We describe the experimental setup and in vitro experimental results.

Ferromagnetic glass-coated microwires with good heating properties for magnetic hyperthermia

The heating properties of Fe71.7Si11B13.4Nb3Ni0.9 amorphous glass-coated microwires are explored for prospective applications in magnetic hyperthermia. We show that a single 5 mm long wire is able to produce a sufficient amount of heat, with the specific loss power (SLP) reaching a value as high as 521 W/g for an AC field of 700 Oe and a frequency of 310 kHz. The large SLP is attributed to the ...

Improvement of Heating Pattern of the Coaxial-slot Antenna for Interstitial Microwave Hyperthermia

Heating Performances of Array Applicator for Interstitial Microwave Hyperthermia: Numerical Simulation and Clinical Trial

INTRODUCTION In recent years, various types of medical applications of microwaves have widely been investigated and reported [1]. In particular, minimally invasive microwave thermal therapies using thin applicators are of a great interest. They are interstitial microwave hyperthermia [2] and microwave coagulation therapy (MCT) [3] for medical treatment of cancer, cardiac catheter ablation for v...

Generation of Controllable Heating Patterns for Interstitial Microwave Hyperthermia by Coaxial-Dipole Antennas

Hyperthermia is one of the modalities for cancer treatment, utilizing the difference of thermal sensitivity between tumor and normal tissue. Interstitial microwave hyperthermia is one of the heating schemes and it is applied to a localized tumor. In the treatments, heating pattern control around antennas are important, especially for the treatment in and around critical organs. This paper intro...
