Microwave Imaging for Breast Cancer Detection

 

X-ray mammography is the most commonly used method for breast cancer detection.  X-ray mammography creates images of the density of breast tissues and these images are used to detect tumors.  According to the institute of medicine, X-ray mammography has been shown in clinical trials to reduce breast cancer deaths, but it is not perfect.  Routine screening in clinical trials resulted in a 25-30% decrease in breast cancer moratlity among women between the ages of 50 and 70.  A lesser benefit was seen among women aged 40‑49.  The benefit of screening mammography for women over 70 was more difficult to assess due to a lack of data [1].

 

“The immense burden of breast cancer and

the inherent limitations of mammography have

been the driving forces behind efforts to develop

technologies for the early detection of breast cancer.”

Microwave imaging is an alternative to X-ray mammography for breast cancer detection.  It relies, at microwave frequencies, on differences in permittivity and conductivity between malignant and normal tissues within the breast.  There are a number of microwave breast imaging methods developed by groups; in Canada at the University of Calgary, and in the United States, Thayer School of Engineering at Dartmouth College, and University of Wisconsin-Madison.  Current research is also underway at the Computational Electromagnetics Research Laboratory, McMaster University.

HAMILTON (CBC) - In 2003, Michael DeGroote, the former CEO of Laidlaw Transport Ltd. donated an eye-opening $105 million to the medical school, transforming it into one of the best-endowed in North America. Degroote's gift was the largest single cash donation in Canadian history and the school was renamed in his honour.

HAMILTON (McMaster Daily News) - McMaster University has been named one of the Top 100 universities in the world--one of only four Canadian universities to make the list, in the annual poll published by China's Shanghai Jiao Tong

University.

 

HAMILTON (McMaster Daily News) - A rare honour has been bestowed on Tamas Terlaky, professor of Computing and Software at McMaster. He has been awarded a University Professorship in the Faculty of Information Technology at the University of Pannonia in Veszprém, Hungary.

Terlaky was recently in Budapest to accept the appointment from Laszlo Solyom, President of Hungary, and Istvan Hiller, Minister of Culture and Education, at a ceremony held across from the Parliament Building.
