Software Design And Development For Neurosurgery Training Sysytem

Neurosurgery operation is an efficient way to treat the neurosurgical diseases, in which the experience of surgeons is very important to decide the success rate of the operation, A virtual operation training system is significant in shortening the training period. However, the existing researches on virtual operation mainly focus on organs with cavity like abdomen and knee, little research has been done on neurosurgical operation, and most of the training systems are far from the real operation environment with weak interaction and poor modeling.To solve the mentioned problems, this paper design a neurosurgical operation training system based on the training platform provided by the minimally invasive medicine(MIM) training center of MOH. The main work of this paper is as follows:1. A FPGA data communication system is designed to collect the spatial posture information of the training platform and transmit it into the neurosurgical operation training software in real time. A three-dimensional virtual scalpel in the software is used to simulate the position and posture of the real scalpel according to the information provided by the data communication system, achieving the united motion in real time.2. The whole brain is visualized to create a vivid operation environment, including the brain white matter and vessels. To further pursue realism of tumor removal, the tumor is texture visualized and the capillary is also built.3. The surgery training software rebuilds white matter, vessels, tumor, texture and capillary in patient brain, which achieve the visualization of the whole brain and the surgery training. While it can also collect the feedback from the training platform to simulate surgical operation.The training system got accepted by the MIM training center of MOH and has been extended in The First Hospital of Zhejiang Province. It reveals that with excellent interaction and brain modeling in vivid operation environment, the system effectively shortens the period of surgeon training for surgery operation and operation path planning, which is a great advance for the success rate of surgical operation.
