X
-rays Mammography is a gold-standard for breast cancer
detection. Mammography has many shortcomes like
painful screening, false results, need biopsy for results
verification etc. Microwave Imaging (MWI) emerges as a
painless alternative technique for breast screening. MWI
works on the principle of reconstruction of image using
inverse scattering radiation from spatial distribution of
dielectric properties of breast tissues. In the present work,
flexible rectangular split antenna, with pyralux polyimide
substrate and 41x23 mm2 in size, were simulated and
characterized the presence of a breast phantom. The
phantom has the dielectric properties of normal breast
tissues and malignant tumors. The resonance frequency of
antenna is 2.2 GHz, which is in compliance with the suitable
frequency range for breast cancer imaging fromthe literature.
Results shows that the electric field distribution is maximum
at around the tumor tissue which is about 350V/m, whereas
in healthy tissue the maximum electric field is 139V/m and
for skin tissues is 103V/m. The electric field is directly related
to the specific absorption rate (SAR) of radiations which is
also higher for tumor tissue with respect to normal.
Speaker Biography
Maryam Liaqat did her Master’s in Physics in 2013 from University of Agriculture,
Pakistan. Currently, she is perusing PhD in Electrical Engineering from Federal
University of Pernambuco, Brazil. She is working on project of microwave antenna
modifications for the detection of breast cancer. Designing flexible antennas for
microwave imaging system, which will be user friendly, cost effective and more precise
in results as compared to x-ray mammography.
