Realistic human head voxel model for brain microwave imaging

Abstract

Numerical human phantoms are the models of human body used in numerical studies. This phantoms have extensive applications in radiation dosimetry as well as electromagnetic analysis. A detailed human body phantom could be considered as a great means for simulation and analysis of the electromagnetic phenomena and electrical devices adjacent to human body. In this work, a human head voxel model is developed for use in CST Studio Suit commercial software pack using an improved voxels set which is extracted from MRI images of a human head. The proposed voxel model contains 256×256×128 voxels elements with dimensions of 1.1×1.1×1.4 mm. Moreover, the dispersive dielectric properties of head tissues as well as their density and thermal conductivity were embedded.
