    摘要： An improved support structure is provided in a method for making objects by the incremental build-up of layers of a deposition material and adjacent support material. The improved support structure includes a first material and a second material placed as a coating upon the first material. The deposition material, first material and second material each preferably have a selected melting point such that the first material melting point is lower than the deposition material melting point and such that the second material melting point is greater than the first material melting point.

    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 one distraction trajectory in view of any discrepancy between the pre-operative plan data and the actual, post-operative data. Assistance in planning and carrying out a bone distraction surgery may be provided to remotely-located surgeons via the Internet using the computer assisted orthopedic surgery planner software at the service provider's location to generate specific surgical plans and simulation models for each surgeon requesting assistance. A physician-friendly 3D modeling approach in the computer assisted/orthopedic surgery planner software according to the present invention reduces the complexities and costs associated with a bone distraction surgery and thus allows more surgeons to practice bone distraction, thereby benefitting more patients in need of bone distraction.

    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，术后外科手术数据可以反馈到计算机辅助矫形外科手术计划软件中，以修正先前指定的一个牵引轨迹。 通过使用计算机辅助整形外科计划软件在服务提供商的位置，可以通过因特网向远程定位的外科医生提供协助规划和执行骨牵引手术，以便为每个外科医生请求帮助生成特定的手术计划和模拟模型。 根据本发明的计算机辅助/矫形外科手术计划软件中的医师友好的3D建模方法降低了与骨牵引手术相关联的复杂性和成本，因此允许更多的外科医生实施骨牵引，从而有利于更多需要骨的患者 分心。
