Journal ArticleDOI
CEM43°C thermal dose thresholds: a potential guide for magnetic resonance radiofrequency exposure levels?
Gerard C. van Rhoon,Theodoros Samaras,Pavel S. Yarmolenko,Mark W. Dewhirst,Esra Neufeld,Niels Kuster +5 more
TL;DR: Standard MRI can cause local heating by radiofrequency absorption and monitoring thermal dose can control risk during MRI, and 9 CEM43°C seems an acceptable thermal dose threshold for most patients.
Journal ArticleDOI
The dependence of electromagnetic far-field absorption on body tissue composition in the frequency range from 300 MHz to 6 GHz
TL;DR: In this paper, the authors used the same methods considering different locations of the body and the respective variations of the tissue structures and dimensions, showing a significant increase of 2.2-4.7 dB of the peak spatial specific absorption rate (SAR) in comparison to the values assessed with standard liquids.
Journal ArticleDOI
Application of a Comprehensive Learning Particle Swarm Optimizer to Unequally Spaced Linear Array Synthesis With Sidelobe Level Suppression and Null Control
TL;DR: The synthesis examples that are presented show that the CLPSO algorithm outperforms the common PSO algorithms and a real-coded genetic algorithm (GA).
Journal ArticleDOI
Arrangement at the nanoscale: Effect on magnetic particle hyperthermia
E. Myrovali,Nikos Maniotis,Antonios Makridis,Anastasia Terzopoulou,V. Ntomprougkidis,Konstantinos Simeonidis,D. Sakellari,Orestis Kalogirou,Theodoros Samaras,Ruslan Salikhov,Marina Spasova,Michael Farle,Ulf Wiedwald,Mavroeidis Angelakeris +13 more
TL;DR: Compared to the non-aligned samples, magnetically aligned samples present enhanced heating efficiency increasing specific loss power value by a factor of two and the anisotropic character of the aligned samples is also reflected to ferromagnetic resonance and static magnetometry measurements.
Journal ArticleDOI
Electromagnetic field exposure assessment in Europe radiofrequency fields (10 MHz-6 GHz).
TL;DR: An overview of the scientific literature on RF EMF exposure in Europe is presented and three population exposure categories (intermittent variable partial body exposure, intermittent variable low-level whole-body (WB) exposure and continuous low- level WB exposure) were recognized by the authors as informative for possible future risk assessment.
