MRI-based anatomical model of the human head for specific absorption rate mapping

the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach

abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...

Experimental Temperature and Specific Absorption Rate Mapping Using MRI in a Transmit-receive Head Coil at 3.0T

Introduction: MRI-based temperature mapping techniques have been applied to detect the temperature changes (∆T ) for a variety of applications, including during the thermoablation of tumors [1], and in verifying minimal temperature increment induced by EEG electrodes and/or its wires during MRI [2]. Although numerical calculations have been used to predict SAR distributions and resulting temper...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

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...
