Two equivalent anthropomorphic breast phantoms were constructed, one for use in
ultrasound elastography and the other in magnetic resonance (MR) elastography. A
complete description of the manufacturing methods is provided. The materials used were oil-
in-gelatin dispersions, where the volume percent oil differentiates the materials, primarily
according to Young's moduli. Values of Young's moduli are in agreement with in vitro ranges
for the corresponding normal and abnormal breast tissues. Ultrasound and nuclear …
