IEEE APS Special Issue
Real-time Microwave Imaging of a Compressed Breast Phantom with Planar Scanning

Daniel Tajik, Electrical and Computer Engineering, McMaster University, Hamilton, Canada
Farzad Foroutan, Electrical and Computer Engineering, McMaster University, Hamilton, Canada
Denys S. Shumakov, Regulatory Operations and Regions Branch, Health Canada, Ontario Canada
Aaron D. Pitcher, Electrical and Computer Engineering, McMaster University, Hamilton, Canada
Natalia K. Nikolova, Electrical and Computer Engineering, McMaster University, Hamilton, Canada

Subject area: Electromagnetic imaging.

Abstract:Abstract:Two real-time reconstruction algorithms, quantitative microwave holography and scattered-power mapping, have been shown to be successful in the imaging of compressed tissue of relatively small thicknesses such as 1 cm and 2 cm. In both cases, planar data acquisition of frequency-swept transmission coefficients has been employed.
