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： Devices and methods for implementing computer-aided surgical procedures and more specifically devices and methods for implementing a computer-aided orthopedic surgery 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. The software model is used to generate a surgical plan, including placement of multifunctional markers, for performing the surgical procedure. After the markers are placed on the patient, an updated image of the patient is taken and used to calculate a final surgical plan for performing the remainder of the surgical procedure. The three-dimensional modeling, surgical planning, and surgery may all take place remote from each other. The various entities may communicate via an electronic communications network such as the Internet.

摘要： An interactive virtual telepresence system allows an Internet user to view three-dimensional objects from any perspective in a studio at a remote server. The system includes several video cameras trained on the three-dimensional objects and a computer that calculates the voxel-representation of the solid. The server broadcasts each camera view and voxel information. A user selects the viewing perspective desired, and the computer at the user's site receives the nearest camera views to the requested perspective and voxel information for the interpolation and renders the selected view.

摘要： An photometric sampling apparatus for an object surface shape and reflectance extraction system includes an array of point light sources spaced apart from one another in an arcuate configuration about a common site at which an object is placed from inspection, an array of extended light sources spaced apart from one another in an arcuate configuration about and oriented in different directions toward the common site, and a viewing device for viewing the object from a single direction when placed at the common site in order to extract information corresponding to the image of the object viewed. The array of point light sources can be activated for emitting light therefrom along different orientation angles toward the object at the common site. The array of extended light sources are generated on the surface of a light-diffusing medium, such as a translucent globe, disposed between the array of point light sources and common site. Each extended source emits light from an area of points unlike each point source which emits light from a single point. A scanner device is connected to the point light sources for sequentially activating them to emit light therefrom. In response to the sequence of emitted light, the extended light sources are generated in a scanning fashion for producing a sequence of images of the object at the viewing device.

摘要： A motor driven vehicle for traversing the interior of a pipe or conduit comprises a pair of arms pivoted to each other at one pair of ends, a drive wheel the axle of which may coincide with the pivot, a swiveling wheel carried at the other end of each arm and a spring positioned to pull the arms toward each other so that the dimension of the vehicle across a pipe is automatically maximized. The vehicle thus tends to position itself on the longest axis of any cross section of the pipe. The drive wheel may be constructed with rim segments which rotate about axes tangent to the means circumference of the rim.

摘要： A camera of a ground-based information dispatch apparatus captures a blind-spot image, showing a region that is a blind spot with respect to a vehicle driver. A vehicle-mounted camera captures a forward-view image corresponding to the viewpoint of the driver, and the forward-view image is transmitted to the information dispatch apparatus together with vehicle position and direction information and camera parameters. Based on the received information, the blind-spot image is converted to a corresponding image having the viewpoint of the vehicle driver, and the forward-view image and viewpoint-converted blind-spot image are combined to form a synthesized image, which is transmitted to the vehicle.
