A Hypothetical Analysis to Study the Variations of Complex Dielectric Permittivity for Detection of Various Stages of Cancer of a Biological Target using Microwave Tomography

Abstract

In recent days, different kinds of Cancerous tumor detection in human body using Microwave Tomography technique (MWT) is picking up huge interest of research among modern day scientists. As all other existing methods like ultrasound, mammography, magnetic resonance imaging (MRI), X - ray imaging etc. are coming up with certain difficulties to patients so Microwave imaging technique is a suitable substitute for that. In this paper, a hypothetical assumption based on the variations of complex dielectric permittivity of the water content of cells with different stages of cancer has been implemented. The complex dielectric permittivities are reconstructed with the help of suitable reconstruction techniques and images have been formed accordingly. Analysing the reconstructed values, a comparative study has been done between a normal cell and different kinds of affected cells. The new approach of this reconstruction algorithm shows a very much efficient way of discriminating all possible kinds of dielectric perturbations for various stages of cancer inside human body. Through this analysis it is shown that the improved version of reconstruction algorithm works well on the hypothetical assumption and the result found is pretty satisfactory and the margin of error is also less, based on the result it is proposed that microwave imaging technique is one of the best methods for detection of the presence cancer cell inside human body.
