Elastography phantom scan. (A) Schematic depiction of the procedure used to validate 3D shear wave velocity on an elastography phantom including discrete targets of known stiffness. The phantom was scanned with the US transducer oriented orthogonal to the contained cylinders and volumetric mapping was implemented using a motion capture system and a reflective marker set attached to the transducer. (B) Heatmap visualization of the volumetric shear wave velocity reconstruction of the four inclusions.
