Novel device for microwave cancer detection
Breast cancer is one of the leading causes of cancer deaths among women and early detection leads to earlier treatment and improve survival rates. As the dominating screening technique X-ray mammography has its limitations, microwave imaging becomes the alternative way for breast cancer detection...

description |
Breast cancer is one of the leading causes of cancer deaths among women and early
detection leads to earlier treatment and improve survival rates. As the dominating
screening technique X-ray mammography has its limitations, microwave imaging
becomes the alternative way for breast cancer detection.
This project introduces a novel device for microwave breast cancer detection using a
flanged parallel-plate waveguide probe. This method is based on detecting the dielectric
contrast between the malignant tumor and the surrounding healthy tissues. The tumor
scatters the signal reflected back from the probe. The backscattered signals received in
the form of S parameters have resonating characteristics in the presence of the tumor.
The location and size of the tumor can also be derived from the measurements.
Simulations using the HFSS software show good return loss within a useful microwave
bandwidth. Experimental validations on breast mimicking phantom material are also
performed, demonstrating the effectiveness of the proposed probe for detecting the
presence of a tumor. |
