    1. Method for reconstructing a 3D presentation

      Method for reconstructing a 3D presentation

      The invention relates to a method for reconstructing a 3D presentation of a hollow organ based on two-dimensional catheter images, comprising: detecting at least two fluoroscopy images at two different angles of the hollow organ; determining a start position of the catheter from the fluoroscopy images in a three-dimensional model of the hollow organ or a catheter guide; determining a probable withdrawal path of the catheter based on the three-dimensional model; withdrawing the catheter while recording the catheter images and assigning a withdrawal length to each catheter image; determining the deviation of the position of the catheter from a central ...

    2. Device and method for intraluminal imaging for the reconstruction of 3D image data sets

      Device and method for intraluminal imaging for the reconstruction of 3D image data sets
      The invention relates to a device and a method for intraluminal imaging. The device features an imaging instrument and a transport unit, with which the imaging instrument is moved in a lumen at a defined speed over a defined distance. The device further features a rigid, i.e. mechanically-stable singly or multiply curved guide pipe, which has an internal diameter matched to the external diameter of the imaging instrument to accommodate and guide the imaging instrument and is made from a material which is transparent for the radiation or to the waves used in imaging. The guide pipe features at ...

    3. Three-dimensional co-registration between intravascular and angiographic data

      Three-dimensional co-registration between intravascular and angiographic data
      A method and appertaining system permit a co-registration between points in a three-dimensional model of a vessel and vascular images obtained by an imaging catheter within the vessel at the respective points. The three-dimensional model is created by utilizing information from at least two external two-dimensional images produced by, e.g., one or more x-ray devices. The three-dimensional model is displayed on an analysis workstation, and a user may view the vascular images at particular points by selecting the appertaining points on the three-dimensional model.

    4. Optical coherence tomography system

      An optical coherence tomography system includes a catheter in which is arranged a plurality of light conducting fibers. It further includes a plurality of optical units. Light from the proximal end to the distal end and signals from the distal end to the proximal end can be transmitted simultaneously in different fibers. Time is saved through the simultaneous signal processing of signals from different fibers. That is advantageous particularly in the imaging, by means of coherence tomography, of blood vessels that have to be occluded for said imaging.
