    • A system and method for intra-operatively providing a surgeon with visual evaluations of possible surgical outcomes ahead of time, and generating simulated data, includes a medical imaging camera, a registration device for registering data to a physical space, and to the medical imaging camera, and a fusion mechanism for fusing the data and the images to generate simulated data. The simulated data (e.g., such as augmented X-ray images) is natural and easy for a surgeon to interpret. In an exemplary implementation, the system preferably includes a data processor which receives a three-dimensional surgical plan or three-dimensional plan of therapy delivery, one or a plurality of two-dimensional intra-operative images, a three-dimensional model of pre-operative data, registration data, and image calibration data. The data processor produces one or a plurality of simulated post-operative images, by integrating a projection of a three-dimensional model of pre-operative data onto one or a plurality of two-dimensional intra-operative images.
    • 一种用于在手术前向外科医生提供可能的手术结果提前视觉评价并产生模拟数据的系统和方法,包括医学成像相机,用于将数据注册到物理空间的登记装置以及医疗成像摄像机 ,以及用于融合数据和图像以生成模拟数据的融合机制。 模拟数据(例如,例如增强的X射线图像)对于外科医生来说是自然而且容易的。 在示例性实施方式中,系统优选地包括数据处理器,其接收三维手术计划或三维治疗递送计划,一个或多个二维手术内图像,三维预处理模型, 操作数据,注册数据和图像校准数据。 数据处理器通过将手术前数据的三维模型的投影集成到一个或多个二维手术图像上来产生一个或多个模拟的术后图像。

    • A hand-held device has access to a three-dimensional geometry database and a GPS receiver, and provides information on the one or more closest features to the device location in the three-dimensional geometry database. The system has data input devices, optionally digital cameras, and a data processor executing a location process. A multiresolution process creates one or more models of the three-dimensional geometry database. The models have a hierarchy of resolutions. The models have vertices, edges and polygons. The multiresolution process preferably associates data to the vertices, edges and polygons. A data processor executes a location process that determines a distance between the position of the hand-held device and corresponding one or more closest features on the hierarchy of resolutions of the database. The data processor produces display commands for displaying data and geometry relative to the one or more closest features. Data input devices are used to collect data that is appended to or replaces data pertaining to the one or more closest features.
    • 手持设备可以访问三维几何数据库和GPS接收器,并且提供关于三维几何数据库中的设备位置的一个或多个最近特征的信息。 该系统具有数据输入设备,可选地数字照相机以及执行定位过程的数据处理器。 多分辨率过程创建三维几何数据库的一个或多个模型。 这些模型具有分辨率的层次结构。 模型具有顶点,边和多边形。 多分辨率处理优选地将数据与顶点,边和多边形相关联。 数据处理器执行确定手持设备的位置与数据库的分辨率层级上相应的一个或多个最近特征之间的距离的位置处理。 数据处理器产生用于显示相对于一个或多个最近特征的数据和几何的显示命令。 数据输入设备用于收集附加到或替换与一个或多个最接近的特征有关的数据的数据。
