Development of breast anthropomorphic phantoms for combined PET-ultrasound elastography imaging

A phantom has been developed for PET/US breast imaging. The phantom reproduces the acoustic and elastic characteristics of human breast tissue, and the different tissues in the phantom can be labeled with
¹⁸
F-FDG. The phantom was imaged with whole body PET/CT and also with the shear wave elastography with Supersonic Imagine Aixplorer system. We also test the phantom for other elastography methods such as static elastography. A 6D magnetic positioning system is used for image matching and fusion. This phantom is developed for ClearPEM/US multimodal breast imaging.
