Application of Microwave Tomography in 3D biomedical examples
MRI-based breast phantom
The data for reconstruction is from the online repository of the Department of Electrical and Computer Engineering at the University
of Wisconsin-Madison (UWCEM). This online repository (http://uwcem.ece.wisc.edu/home.htm) provides a database of anatomically realistic MRI-based numerical breast phantoms,
which capture the structural heterogeneity of normal breast tissue and incorporate the realistic dispersive dielectric properties of normal breast tissue from 0.5 to 20 GHz. Here we use single frequency
2GHz.
