Model of the abdominal US phantom used for validation. The blue phantom (Blue Phantom, Kirkland, WA) is made of silicone with acoustic properties similar to human tissue. The phantom has different cystic regions with different echogenicity. The phantom was mounted on a casing simulating a human torso that can be used to explore the region using either an endoscopic or laparoscopic probe
