Electromagnetic hyperthermia as a potent adjuvant for conventional cancer therapies can be considered valuable in modern oncology, as its task is to thermally destroy cancer cells exposed to high-frequency electromagnetic fields. Hyperthermia treatment planning based on computer in silico simulations has the potential to improve the localized heating of breast tissues through the use of the phased-array...
The following paper describes the valid optimization problem of multi-element circular array that contains 16 equal-length dipole antennas surrounding given two-spherical object. The task of the authors was to maximize the specific absorption rate (SAR) inside the inner object, while maintaining its minimum value in the external sphere. The proposed approach includes changes in the powers and phases...
The paper considers the optimization issue of eight dipole antennas array surrounding the tested object. The goal was to maximize the specific absorption rate (SAR) in the target volume, while minimizing the same parameter in the outer object. The SAR optimization was prepared by means of the powers (amplitudes) and the phases used to excite the individual antenna elements of the array. Presented...
The article presents the experimental study of magnetic fluid hyperthermia (MFH) utilizing magnetite nanoparticles with diameter of 15.2 nm. Temperature measurements of the ferrofluid samples were carried out in real measurement system using parallel resonance phenomenon. Based on the obtained temperature curves the basic heating parameters of ferrofluid, namely the Specific Absorption Rate (SAR)...
The paper describes the assessment of exposure of a six-year-old male patient with a titanium bar implanted after Nuss procedure to microwave radiation with frequency of 2.45 GHz. The local SAR concentrations inside the boy's trunk for two variants of plane wave polarizations with regard to the titanium implant have been considered. It was demonstrated that an analyzed concave bar-implant poses no...
