  • Method for the simulation of the haptic of an interaction of a guided object with a virtual three-dimensional object
    Patent number: 8396698
    Abstract: The object of the instant invention is a method for simulating the haptics of an interaction of an object guided by a user, hereinafter referred to as tool, with a virtual three-dimensional object, in particular the scanning of the surface of the simulated object and/or the penetration of the guided object into the simulated object, under material removal, if applicable.
    Type: Grant
    Filed: May 6, 2008
    Date of Patent: March 12, 2013
    Assignee: Universitatsklinkum Hamburg-Eppendorf
    Inventors: Andreas Petersik, Karl-Heinz Hohne, Bernhard Pflesser, Andreas Pommert, Ulf Tiede
  • Method and Device for 3d-Navigation On Layers of Images
    Publication number: 20100284594
    Abstract: The invention relates to a device and to a method for representing 2D-layers of images of internal structures. The invention enables the physical expansion of a tool to be represented in a 3D manner in 2D layers of images of internal structures and to represent modifications on said internal structures, in particular bone structures, by means of an operation tool for preparing, performing, displaying, reproducing, further processing or learning a surgical operation.

  • Method and device for knowledge based representation and display of three dimensional objects
    Patent number: 5623586
    Abstract: The method serves to represent a three dimensional object and is especially adapted for use in the field of medical technology. At least a portion of the object is spatially recorded relative to at least one geometric parameter. Hereby a sequence of picture units is generated. The spatial assignment of the parameter is stored in a storage device and conveyed for visualization to a display device. After acquisition of at least one portion of the space assigned to the object the object is subdivided into volume elements, the coordinates of the volume elements as well as at least one attribute characterizing the volume elements is subsequently stored. Subsequently an assignment of the volume elements to spatial substructures with help of the attributes is performed and at visualization a selectable assignment of the volume elements is realized in dependence of at least one of the attributes.
