3D printed Breast Phantoms. Phantoms were printed in VeroClear (a), TangoPlus (b) and a new combination of TissueMatrix with a coating of VeroClear at 600 μm (c). Ultrasound (US) image (d) of the TangoPlus phantom demonstrates lack of sound penetration. Images obtained with standoff pad (e) shows similar findings. Both VeroClear and TissueMatrix phantoms had similar results on US imaging
