Influence of information about specific absorption rate (SAR) upon customers' purchase decisions and safety evaluation of mobile phones.

This study investigated whether the SAR value is a purchase-relevant characteristic of mobile phones for laypersons and what effect the disclosure of a precautionary SAR value has on laypersons' risk perception. The study consisted of two parts: Study part 1 used a conjoint analysis design to explore the relevance of the SAR value and other features of mobile phones for an intended buying decis...

Specific Absorption Rate (SAR) in the head of Tablet user's

Wireless communication devices such as tablets are increasing and developing rapidly. The effects of the electromagnetic (EM) waves in the human body from the wireless communication devices have been paid attention. It is well known that the absorption of electromagnetic waves on the human head for a certain period of time may lead to health problems such as headaches, or even worse, significan...

Reduced specific absorption rate (SAR) pseudo-continuous arterial spin labeling

Introduction: A reduced specific absorption rate (SAR) version of pseudo-continuous arterial spin labeling (pCASL) pulse sequence (1,2) is designed and implemented. Using a simulation study, a set of pCASL pulse sequence parameters is found that allows reducing the flip angle of pCASL radio frequency (RF) pulses (and consequently SAR) without losing the inversion efficiency. The proposed set of...

Reduction of Specific Absorption Rate (sar) in the Human Head with Ferrite Material and Metamaterial

The electromagnetic interface between the antenna and the human head is reduced with ferrite materials and metamaterials. The reduction of Specific Absorption Rate (SAR) with materials and metamaterials is performed by the finite-difference time-domain method with Lossy-Drude model by CST Microwave Studio. The metamaterials can be achieved by arranging split ring resonators (SRRs) periodically....

Designing Rf Pulses with Optimal Specific Absorption Rate (sar) Characteristics and Exploring Excitation Fidelity, Sar and Pulse Duration Tradeoffs

INTRODUCTION: Recent methods of designing RF pulses for multi-coil TX systems have focused on solving regularized systems of equations. These techniques linearize the equations relating the RF waveforms to the resulting excitation and then penalize RF candidates with high peak and root-mean-square (RMS) voltages (VP and VRMS, respectively) in an attempt to limit SAR [1,2]. This is sensible beca...
