Abstract :
We use time reversal microwave imaging to detect and classify benign and malignant breast cancer lesions in numerical phantoms. We employed Time Reversal MUSIC (TR MUSIC) method to detect breast tumors in the presence of adipose and fibroglandular breast tissues. The classification of tumors is made based on the analysis of singular values of the multistatic matrix. We consider two different bands of frequencies 0.9-3 GHz and 3-10 GHz to show that in 0.9-3 GHz frequency band some distinct features for classification for breast tumors can be extracted.
