Estimation of Breast Tumor Conductivity using Parabolic Phase Fitting
Year: 2012
Type: conference-paper
Abstract: According to ex vivo studies, breast tumors exhibit a significantlyaltered electric conductivity. This feature opens the chance to increase the specificity of breast tumor characterization with MRI. Theelectric conductivity can be measured in vivo using Electric Properties Tomography (EPT). EPT has shown its potential in phantom, volunteer, and initial clinical studies. However, the complex frayed structure of fat and ductile tissue in the breast hampers the straight-forward application of EPT, based on the second derivative of the RFTX phase. In this study, a new EPT reconstruction algorithm, based on fitting local parabolic functions on the TX phase, is developed and applied to example breast tumors.
