“…Chmarra et al 17 developed an agarose based liver phantom to get images from ultrasound imaging, MRI, and CT modalities similar to those of patients. Chen et al 9 created a polyvinyl alcohol (PVA) brain phantom that could be used to validate the results of ultrasound, MRI, and CT imaging. Table I summarizes results of prior research on some mechanical and medical imaging properties of nine common tissue-mimicking materials [agar, agarose, gelatin, gellan gum, PVA, PVC, room-temperature vulcanizing (RTV) polymerized siloxanes (silicone), polydimethylsiloxane (PDMS), and polyurethane (PU)] and five types of tissues from human and animals (liver, brain, fat, muscle, and prostate).…”
