摘要： A method and a system of generating an image sequence of an object within a scene. According to one embodiment, the method includes capturing an image (images I1-N) of the object with a plurality of camera systems, wherein the camera systems are positioned around the scene. Next, the method includes 2D projective transforming certain of the images (I2-N) such that a point of interest in each of the images is at a same position as a point of interest in a first image (I1) from one of the camera systems. The method further includes outputting the transformed images (I2'-N') and the first image (I1) in a sequence corresponding to a positioning of the corresponding camera systems around the scene.

摘要： A computer assisted orthopedic surgery planner software for generation of 3D (three dimensional) solid bone models from two or more 2D (two dimensional) X-ray images of a patient's bone. The computer assisted orthopedic surgery planner software reconstructs the bone contours by starting with a 3D template bone and deforming the 3D template bone to substantially match the geometry of the patient's bone. A surgical planner and simulator module of the computer assisted orthopedic surgery planner software generates a simulated surgery plan showing the animation of the bone distraction process, the type and the size of the fixator frame to be mounted on the patient's bone, the frame mounting plan, the osteotomy/coricotomy site location and the day-by-day length adjustment schedule for each fixator strut. All bone models and surgery plans are shown as 3D graphics on a computer screen to provide realistic, pre-surgery guidance to the surgeon. Post-operative surgical data may be fed back into the computer assisted orthopedic surgery planner software to revise the earlier specified bone distraction trajectory in view of any discrepancy between the pre-operative plan data and the actual, post-operative data.
摘要翻译：一种用于从患者骨骼的两个或更多个2D（二维）X射线图像生成3D（三维）实体骨模型的计算机辅助矫形外科计划软件。计算机辅助的整形外科计划软件通过从3D模板骨骼开始并使3D模板骨头变形以使患者骨骼的几何形状基本匹配来重建骨骼轮廓。计算机辅助矫形外科手术计划软件的外科计划器和模拟器模块产生模拟手术计划，显示骨牵引过程的动画，要安装在患者骨骼上的固定器框架的类型和尺寸，框架安装计划，截骨/切开术位置和每个固定器支柱的逐日长度调整计划。所有骨模型和手术计划都在计算机屏幕上显示为3D图形，为外科医生提供逼真的手术前指导。考虑到手术前计划数据与实际手术后数据之间的任何差异，术后手术数据可以反馈到计算机辅助矫形外科计划软件中，以修正早期指定的骨牵引轨迹。

摘要： Devices and methods implement computer-aided orthopedic surgical procedures (50) utilizing intra-operative feedback. A three-dimensional model of an area of a patient upon which a surgical procedure is to be performed is modeled using software techniques (52). The software model is used to generate a surgical plan (54), including placement of multifunctional markers. After the markers are placed on the patient, an updated image of the patient is taken and used to calculate a final surgical plan (70) for performing the remainder of the surgical planning, and surgery (56) may all take place remote from each other. The various entities may communicate via an electronic communications network such as the Internet.
