Modeling and Simulation of Uterine Fibroids Based on Virtual Reality

Abstract— This paper introduces a virtual interactive system to visualize the growth of uterine fibroids and its impact on the surrounding soft tissue, in which virtual reality, soft tissue deformation are mainly used. The system uses Autodesk Maya to build three-dimensional models of standard uterine and common uterine fibroids, then simulates the growth of uterine fibroids and the deformation of soft tissues through Unity. Soft tissue deformation is mainly based on weighted average normal method: Collision detection algorithm and influence radius are used to determine the deformation region of organ mesh; By calculating the weighted average normal of the deformation area, the deformation direction is determined, and the gauss smoothing is transformed into a weighted factor to generate a new deformation mesh. The system can simulate the growth of common uterine fibroids, and can be used for presentation and prediction of uterine fibroids, physician training, surgical assistance, electronic medical records, etc.

Index Terms— virtual reality, soft tissue deformation, weighted average normal, collision detection, gaussian smoothing..
