Breast phantom with a conductive skin layer and conductive 3D-printed anatomical structures for microwave imaging

We present a breast phantom for experimental medical microwave imaging. The phantom structures separating the tissue mimicking liquids are 3D-printed based on conductive materials. The skin is cast by silicone composites with carbon powder and graphite. In comparison to 3D printing with common plastic, this approach allows the simulation of anatomical breast structures with improved dielectric characteristics.
