摘要： Ultrasound's value in the neurosurgical operating room is maximized when fused with pre-operative images, The disclosed system enables real-time multimodal image fusion by estimating the ultrasound's pose with use of an image- based registration constrained by sensor measurements and pre-operative image data. Once the ultrasound data is collected and viewed, it can be used to update the pre-operative image, and make changes to the pre-operative plan. If a surgical navigation system is available for integration, the system has the capacity to produce a 3D ultrasound volume, probe-to-tracker calibration, as well as an optical-to-patient registration. This 3D ultrasound volume, and optical-to-patient registration can be updated with conventional deformable registration algorithms and tracked ultrasound data from the surgical navigation system. The system can also enable real-time image-guidance of tools visible under ultrasound by providing context from the registered pre-operative image when said tools are instrumented with sensors to help constrain their pose.
摘要翻译：当与手术前图像融合时，神经外科手术室中的超声波值最大化。所公开的系统通过使用基于图像的配准来估计超声波的姿态，从而实现实时多模式图像融合传感器测量和术前图像数据。一旦收集并查看超声数据，就可以用它来更新术前图像，并对术前计划进行修改。如果手术导航系统可用于整合，系统可以生成3D超声波体积，探头 - 跟踪器校准以及光学到病人注册。这种3D超声体积和光学到病人的注册可以使用传统的可变形注册算法和来自手术导航系统的跟踪超声数据进行更新。该系统还可以实现在超声波下可见的工具的实时图像引导，通过从注册的术前图像提供上下文，当所述工具装备有传感器以帮助约束其姿势时。
