Lab VIEW-based planar multilayered model for estimation of the absorbed energy inside biological tissues

Abstract

This article describes the analysis of the electromagnetic absorption and scattering properties of a planar multilayered structure, representing simplified models of human tissues. A step-by-step approach for the implementation of a planar multilayered code using the Lab VIEW environment is presented. The effects of the fat layer on the specific absorption rate (SAR) deposition in two models of human tissues were considered. The first model was a three-layered (skin-fat-muscle) tissue model. The second model was a human-head model, comprised of seven different tissues of skin, fat, muscle, bone, dura, cerebrospinal fluid (CSF), and brain. The simulation results were evaluated, and showed the fat-layer effects on the specific absorption rate deposition in human tissues. The graphical nature of the Lab VIEW programming environment makes it very easy to create a sophisticated application in a minimum amount of time, especially when compared to designing graphical user interfaces in a low-level programming language.
