Simulation-Based Virtual Reality (VR) Visualization of Cerebral Aneurysms Treated with Stents

脑动脉瘤（或脑动脉瘤）是血管中异常的充满血液的隆起。如果不治疗，脑动脉瘤破裂的风险很高，并可能导致出血性中风-加拿大残疾和死亡的主要原因。血流导向支架（插入动脉中的小网状管）通过降低破裂风险而显示出相当大的治疗脑动脉瘤的前景。尽管用这种支架治疗的结果令人鼓舞，但据报道，治疗后并发症的发生率为15- 35%。该项目旨在开发一种基于虚拟现实（VR）技术的支架治疗结果可视化的新方法，该技术允许人们像3D电影一样看到支架治疗结果。该项目的成功将帮助神经外科医生识别可能导致既往治疗患者成功/失败的因素，并预测和战略性计划动脉瘤患者的支架治疗或再治疗。它还将极大地促进/增强医学生/住院医生和动脉瘤患者对动脉瘤支架治疗的沉浸式学习/理解。我们的目标的成功完成将意味着LUXSONIC Technologies Inc.作为该项目的工业合作伙伴，SK萨斯卡通（https：//www.luxsonic.ca/;以下简称LUXSONIC）将立即获得技术和经济效益，因为该项目将有助于推出一种新的基于VR的医疗教育/培训和医疗保健产品。

A cerebral aneurysm (or brain aneurysm) is an abnormal blood-filled bulge in a blood vessel. If untreated, a cerebral aneurysm presents a high risk of rupture, and may lead to haemorrhagic stroke - a leading cause of disability and death in Canada. Flow-diverting stents (small mesh tubes inserted into the artery) show considerable promise for the treatment of cerebral aneurysms by lowering rupture risk. Despite encouraging results of treatment with such stents, post-treatment complications have been reported at rates of 15-35%. The project aims to develop a novel way to visualize the stent-treatment outcomes based on virtual reality (VR) technology, which allows one to see the stent-treatment outcomes very much like 3D movies. The success of this project will help neurosurgeons discern the factors that might contribute to the success/failure of previously treated patients and to predict and strategically plan stent treatment or re-treatment for aneurysm patients. It will also greatly facilitate/enhance the immersive learning/understanding of aneurysm treatment with stents for medical students/residents and aneurysm patients. The successful completion of our objectives will mean LUXSONIC Technologies Inc. of Saskatoon, SK (https://www.luxsonic.ca/; hereafter LUXSONIC), the industrial partner of this project, will reap immediate technological and economic benefits because the project will help to launch a new VR-based product for medical education/training and health care.
