Development of a virtual reality model of the normal female pelvic floor

The anatomy of the pelvic floor is complex and difficult to visualize. Thus, a virtual reality (VR) model could be useful both for teaching and research. The aim of this project was to develop a static three-dimensional (3-D) VR model of the normal female pelvic floor. An asymptomatic nulliparous twenty-three year old female with no urinary incontinence symptoms underwent a high resolution pelvic floor magnetic resonance imaging (MRI) scan. Manual segmentation of selected pelvic floor structures were performed. 3-D models were then created and edited. The completed models were displayed on an ImmersaDesk VR system. Stereovision glasses were used to enhance the model while a receiver tracked head position. The VR models accurately displayed the anatomy of the female pelvic floor. A 3-D VR model of the female pelvic floor could be used to enhance our understanding of anatomy and physiology of this complex part of the body. It could be used as a tool for both teaching and research, promoting improved treatment of pelvic floor pathologies.
