A phantom was constructed to simulate the in vivo situation of gallstone detection. Gallstone specimens from 37 patients were scanned. All gallstones cast acoustic shadows, regardless of the specific properties of the stones. Experimental evidence concerning factors that affect the detection of acoustic shadows from gallstones is discussed.
