Abstract:: Abstract: Objective To reconstruct a three-dimensional model of biliary tract and its adjacent structure using Mimics software for providing a real model basis for medical and engineering integration application such as magnetic induction hyperthermia. Methods The computed tomography (CT) and magnetic resonance cholangiopancreatography (MRCP) scan data were collected from patients with lower biliary obstruction. Image segmentation, section filling and mask editing were carried out in Mimics software. The digital model of biliary tract and its adjacent structure was constructed and then input into COMSOL software for finite element discretization to verify the potential of the model for simulation operation. Results The dilated biliary tract, liver, hepatic venous system, gallbladder, pancreatic duct, and part of duodenum at the junction of biliopancreatic duct were completely constructed. The resolution of the whole model was 1 mm, and it was in stereolithography (STL) format of digital model file, which enabled the model be applied to various computer-aided design software such as COMSOL and AUTO-CAD. Conclusion A high-precision three-dimensional reconstruction model of the biliary tract and its adjacent structures can be accurately established using Mimics software, which creates a foundation for the subsequent multidisciplinary application of the model in biliary tract diseases, such as magnetic induction hyperthermia for biliary tract tumors.
