Virtual surgery system for abdominal organs based on VR helmet

Now Days doctors interpret the human body abdomen via CT images, which is always lack of intuitive, three-dimensional viewing. Statistics show that 80% of clinical errors are caused by human error. Therefore surgical training for young surgeons is very important to their experience growth. In order to observe the body structure of the human body efficiently and improve the technical proficiency of doctors, this paper designs a surgical system for abdominal organs based on VR helmet. Using 3D Labeling algorithm and time varying phase difference algorithm, the system can automatically segment the organs in medical image and transfer the reconstruction of the human abdominal body into three-dimensional model, from which a VR helmet could perform a real-time visualization of the human organs in different viewpoints. Our system provides a virtual tool set (scalpel, surgical clamp) that enable the use of collision detection and cutting algorithm to achieve the cutting effects of the abdominal organs. Experimental results show that our system are robust to achieve the establishment of three-dimensional abdominal organ model, and virtual surgery tools could help doctors to simulate the operation completely together with the use of force-feedback device.
