    • A method and system is disclosed for registering two dimensional fluoroscopic images with a three dimensional model of a surgical tissue of interest. The method includes steps of: (a) generating, from CT or MRI data, a three dimensional model of a surgical tissue of interest; (b) obtaining at least two, two dimensional, preferably fluoroscopic, x-ray images representing at least two views of the surgical tissue of interest, the images containing radio-opaque markers for associating an image coordinate system with a surgical (robot) coordinate system; (c) detecting the presence of contours of the surgical tissue of interest in each of the at least two views; (d) deriving bundles of three dimensional lines that pass through the detected contours; and (e) interactively matching three dimensional points on three dimensional silhouette curves obtained from the three dimensional model with the bundles of three dimensional lines until the three dimensional model is registered within the surgical coordinate system to a predetermined level of accuracy. The step of iteratively matching includes steps of: defining a distance between surfaces of the model and a beam of three dimensional lines that approach the surfaces; and finding a pose of the surfaces that minimizes a distance to the lines using, preferably, a statistically robust method, thereby providing a desired registration between a surgical robot and a preoperative treatment plan.
    • 公开了一种用于使用感兴趣的外科组织的三维模型记录二维荧光透视图像的方法和系统。 该方法包括以下步骤:(a)从CT或MRI数据生成感兴趣的手术组织的三维模型; (b)获得表示感兴趣的手术组织的至少两个视图的至少两个,二维,优选荧光透视的X射线图像,所述图像包含用于将图像坐标系与手术(机器人)坐标相关联的不透射线标记 系统; (c)在所述至少两个视图中的每一个中检测感兴趣的手术组织的轮廓的存在; (d)导出通过检测到的轮廓的三维线束; 以及(e)将由三维模型获得的三维轮廓曲线上的三维点交互地匹配三维线,直到三维模型在外科坐标系内登记到预定的精度水平。 迭代匹配的步骤包括以下步骤:定义模型的表面之间的距离和接近表面的三维线束; 并且使用优选地统计上鲁棒的方法来找到使距离线的距离最小化的表面的姿态,从而在手术机器人和术前治疗计划之间提供期望的配准。

    • According to some embodiments of the present invention, a system for stereo reconstruction from a monoscopic endoscope is provided. The monoscopic endoscope comprising an image pick-up element at a distal end thereof and a working channel defined by a body of the monoscopic endoscope. The working channel provides a port at the distal end of the monoscopic endoscope. The system for stereo reconstruction comprises a light patterning component configured to be disposed within the working channel of the monoscopic endoscope such that a light emitting end of the light patterning component will be fixed with a defined relative distance from the distal end of the image pick-up element. The system for stereo reconstruction also includes a data processor adapted to be in communication with the image pick-up element. The light patterning component forms a pattern of light that is projected onto a region of interest. The data processor is configured to receive an image signal of the region of interest that includes the pattern, and determine a distance from the endoscope to the region of interest based on the image signal and based on the defined relative distance between the light emitting end of the light patterning component and the distal end of the image pick-up element.
