Abstract
As a popular technology in the field of human-computer interaction, virtual reality (VR) brings a brand new sensory experience to users by generating the environment. In recent years, while introducing the application of virtual reality technology, researchers have done a lot of work around virtual reality in many fields, such as the application of virtual reality technology in medical procedures. Combining the immersive and expandable features of virtual reality can improve the safety and accuracy of surgery. This article mainly introduces the application of 3D-CTA virtual reality technology in intracranial aneurysm surgery and aims to provide some ideas and directions for the improvement and progress of intracranial aneurysm surgery. This paper presents a research method based on virtual reality technology 3D-CTA in intracranial aneurysm surgery, including the application overview of 3D-CTA in intracranial aneurysm surgery and the virtual reality algorithm based on 3D-CTA for intracranial arteries. In addition, there is also the application of virtual reality CTA technology in the design of the intracranial aneurysm application system. Experimental results show that the average accuracy of 3D-CTA diagnosis based on virtual reality is 90.81%, and it can be put into use in the next step.
Highlights
Intracranial aneurysm (IA) refers to the abnormal expansion of the walls of cerebral arteries, forming tumors similar to protrusions. is is a general cerebrovascular disease and the most common subarachnoid hemorrhage (SAH)
Method of Obtaining Head Posture. e PATRIOT device transmitter is installed on the upper middle of the user’s forehead, so that the signal from the transmitter can better simulate personal visual contact. e PATRIOT receiver is placed directly behind the screen, and the operator’s posture data is programmed to obtain the Developer Interface (PDI) provided by the PATRIOT device by using the Polhemus application program interface. is study uses the BO-OL ReadSinglePnoBuf provided by it. e first parameter of the function is the PBYTE type indicator, which is used to display the size of the storage unit receiver that stores the data of the frame obtained from it and the size of the second parameter storage unit
(2) It can be seen from the chart that among the three numerical calculation methods of the improved Euler algorithm, the traditional Euler algorithm, and the Runge-Kutta algorithm, the improved Euler method has the shortest single-step execution time and the fastest deformation frame rate. e evaluation of the effect of virtual surgery simulation includes three aspects: visual fidelity, tactile fidelity, and real time. e improved Euler method is adopted, the execution time is short, and the calculation efficiency is high, which fully meets the requirements of virtual surgery simulation [35]
Summary
Intracranial aneurysm (IA) refers to the abnormal expansion of the walls of cerebral arteries, forming tumors similar to protrusions. is is a general cerebrovascular disease and the most common subarachnoid hemorrhage (SAH). The incidence of intracranial aneurysms is increasing year by year, and the third category is cerebrovascular disorders, followed by ischemic stroke and hypertensive intracerebral hemorrhage (HICH). Once an intracranial aneurysm ruptures and hemorrhages, the prognosis is often poor. About 1/ 3 of the patients have died when they can be treated in the hospital in the future, 1/3 of the patients died in the hospital, and the other 1/3 of the patients received active treatment. The fatality rate of the aneurysm after rupture and bleeding can be as high as 60% to 80%. With the transformation of medical models and traditional medical concepts, neurosurgery has changed from treating the disease itself to maximizing the removal of the disease while reducing the impact of surgery on nerve function
