Materials and MethodZZFish bones from two species were collected and sizes were measured. Pork meat loaf was placed flat into a plastic box containing plaster cast and bones were laid over the meat layer. nother layer of meat was placed on the bones, then another layer of plaster cast, and the final layer of meat were placed. The meat-bone sandwich was regarded as a fish bone foreign body model of esophagus. The model was imaged using computed tomography (CT) scan and the CT data were reconstructed three-dimensionally making multi-planar reconstruction, maximal intensity projection, and volume rendering images. We tried to find tools to detect the shape and lying position of the FF model. The above tools were applied to 3 FF cases to verify effectiveness of the tools. ResultsZZMulti-planar reconstruction, maximal intensity projection, and volume rendering images were reconstructed easily. fter single or more processing, all of the bones could be detected. The shape and lying positions could be detected using tools made from FF models. ConclusionZZReconstructed images of CT data readily enabled the detection of fish bone in the esophageal model and real cases.
