Breast cancer detection using Forward Scattering Radar technique

Abstract

This paper presents an initial investigation for breast cancer detection using a special mode of bistatic radar system known as Forward Scattering Radar (FSR). The proposed method analyzes the Doppler frequency in the received signal scattered from the tumor for cancer detection and localization. Three systems of architectures were analyzed which determined by the mechanical movement of transmitter or receiver or both. This paper also discusses an initial simulated result by using CST Microwave Studio as a feasibility study of utilizing FSR for breast cancer detection. It is shown that by investigating the unique character of Radar Cross Section (RCS) for breast tissue and tumor of FSR a cancer can be predicted. Electromagnetic model including fatty tissue and a tumor were simulated to obtain RCS parameter and analyzed as well as compared with whose fatty tissue without cancerous lesion to pinpoint the presence of tumor from its FSR signature. The result shows a significant different between these two models in FS RCS.

A Modified Compact Flexible Vivaldi Antenna Array Design for Microwave Breast Cancer Detection

“…However, this method is an invasive and ionizing technique. It also yields high false-negative rates [4,5]. Other non-ionizing detection methods, such as Magnetic Resonance Imaging (MRI), can be used for early-stage breast cancer diagnoses.…”

Breast cancer detection using K-nearest neighbors data mining method obtained from the bow-tie antenna dataset

“…A kind of disease causing body cells to change and grow uncontrollably is called as cancer, infestation, or metastasis, which cancer cells diffuse to other tissues or organs in the body by lymph or blood . There are various cancer types; namely breast cancer, skin cancer, lung cancer, kidney cancer, prostate cancer, thyroid cancer, etc.…”

“…But there is no accurate method for detecting breast cancer. X‐ray mammography is currently one of the widespread detection methods . However, it is well known that X‐ray mammography suffers from constraints in sensitivity and specificity.…”

“…Hybrid methods refer microwave energy to heat tumors in a fast way and it has ultrasound transducers to discover pressure waves generated by the heated tissues' expansion. The other method is Active Microwave Imaging (AMI) including Microwave Tomography and Ultra‐Wideband (UWB) radar‐based approach due to low cost and non‐ionizing feature . UWB radar‐based approach systems have been interested by many researchers.…”
