Tumor tracking with microwave breast imaging using refined patient specific prior information

Microwave imaging has been proposed as a complementary method for breast imaging as it is sensitive to the electrical properties of tissues. Two techniques that exploit imaging at microwave frequencies are radar-based imaging and microwave tomography (MWT). A combined radar/MWT method has been developed jointly between the Universities of Manitoba and Calgary (Baran et. al., Pier, 149, 161–171, 2014) for monitoring tumor size changes to assess treatment progress. The findings of a comprehensive study investigating how patient specific prior information affects image quality using this combined technique are presented.
