Development of a 3D blood vessel model for the simulation of the minimally invasive surgery

摘要

In this paper, we build one VR system which is used for the training of the interns to operate the Robotic Catheter System and improve the operational experience and auxiliary medical process for the minimally invasive surgery, uses the open source code DCMTK to read the information about DICOM file and carry out the CT image segmentation for the Virtual Reality based Robotic Catheter System. In order to get the vessel model, apply Open Scene Graph (OSG) to realize the 3D image output and catheter control of the Virtual Reality System, according to the 4 area method, blood vessel data can get from the text file,. Finally, the vessel model is used in the VR simulator for training surgery and the system is fit for training unskilled surgeons to do the operation of intravascular neurosurgery.
