目的：先进的磁共振成像采集方法（如4D相对比磁共振成像（4D pcMRI））在评估脑动脉瘤血流动力学方面得到了广泛的应用。其中一个目标是确定预测动脉瘤破裂的血流动力学情景。由于4D pcMRI技术的技术复杂性，在提取和传达MRI图像数据中包含的丰富信息方面存在挑战，特别是向卫生专业人员和基础科学家组成的多学科团队。方法：在这里，我们介绍了一种新的资源，一种市售的光学透明头戴式显示器，它允许通过计算机生成的虚拟物体来增强现实世界。结果：一种图像处理算法预先将3D旋转血管造影数据、3D飞行时间MRI数据和4D pcMRI数据获得的3D表面模型整合到增强现实环境中。这种新方法成功地对6例脑动脉瘤患者在分流治疗前后获得的血流数据进行了评估。结论：增强现实可能成为可视化复杂医疗数据的一种附加手段，特别是这里所示的复杂流程。
OBJECTIVE: Advanced magnetic resonance imaging I) acquisition methods such as 4D phase contrast magnetic resonance imaging (4D pcMRI) have found widespread applications in assessing hemodynamics in cerebral aneurysms. One of the goals is the identification of a hemodynamic scenario predictive of aneurysm rupture. Because of the technical complexity the 4D pcMRI technology, challenges exist in extracting and communicating the wealth of information contained in the MRI image data, in particular, to a multidisciplinary team of health professionals and basic scientists.METHODS: Here we introduce a new resource in the An of a commercially available optical see-through headmounted display, which allows augmenting the real world by computer-generated virtual objects.RESULTS: An image processing algorithm was prefor integrating 3D surface models derived from 3D rotational angiography data, 3D time-of-flight MRI data, and 4D pcMRI data into the augmented reality environment This new approach was successfully evaluated on blood flow data acquired before and after flow diverter treatment in 6 patients harboring a cerebral aneurysm.CONCLUSIONS: Augmented reality may become an additional means for visualizing complex medical data, in particular complex flows as illustrated here.
