Professor Zhipeng Wu at the University of Manchester has developed a novel radiofrequency scanner to be used for real-time breast tumor detection. Unlike traditional mammography, which relies on the varying X-ray attenuation properties of tissues to produce image contrast, the portable scanner uses radiofrequency waves to perform complex permittivity mapping of tissue. Benign and malignant breast tumors have (complex) permittivity characteristics that differ from surrounding tissue, and although the scanner is not able to differentiate between benign and malignant structures, it could prove to be a sensitive and inexpensive screening tool. Such a device could potentially improve breast cancer detection in women under 50 and would be very welcome in the developing world.
