摘要： A system for planning a percutaneous procedure provides a patient 3-dimensional image data set within which an instrument trajectory is defined, for example, by selecting a skin entry point and a target point. A line, or “planned path,” is generated between the points. The system determines whether the path can be targeted so an optical axis of a movable arm coincides with the path so that a laser can be used for instrument guidance or whether a planned path can be targeted so that a C-arm can be made to coincide with the path so that the extension of the path is projected onto a radiation detector, using x-ray radiation. If neither laser guidance or x-ray guidance can be used, the path is replanned.

摘要： In a method for visualizing placement of a stent in an aorta of a patient with reduced use of contrast agent, a 3D volume image of the aorta of the patient is provided from a CT scan before placing the stent. An angiography system with a C-arm is provided to take 2D images of the patient. A computer is provided having registration software for registering the 3D volume image and 2D images taken by the angiography system. A first segmentation is performed on the 3D volume image to segment the aorta from remaining parts of the 3D image. A second segmentation is performed using the first segmentation on the 3D volume image to segment a bony structure of the patient from remaining parts of the 3D volume image. A first 2D image of the aorta is obtained from a first direction with use of a contrast agent. A second 2D image is obtained from a second direction but without use of contrast agent. The segmented aorta in the 3D volume image is registered to the C-arm to create a registered 3D volume image by registering the first 2D image to the segmented aorta and registering the second 2D image to the segmented bony structure. The stent is placed in the aorta while observing on the angiography system a third continuous 2D image taken by the angiography system superimposed on the registered 3D volume image.

摘要： A number of two-dimensional projection images of a three-dimensional examination object are assigned image times and imaging parameters. The projection images are combined into reconstruction groups including projection images with image times specifically assigned or within a time interval specific to the reconstruction groups. The reconstruction groups are determined in such a way that three-dimensional reconstructions of the examination object with direction-dependent local resolution can be determined based on the projection images of the reconstruction groups; it is not possible to determine three-dimensional reconstructions of the examination object with direction-independent local resolution. Three-dimensional reconstructions of the examination are determined based on the projection images of the reconstruction groups. Reconstruction times are determined based on the image times assigned to the projection images of the reconstruction groups and assigned to the three-dimensional reconstructions. Further analyses are performed as a function of the temporal sequence of the three-dimensional reconstructions.

摘要： A method for forming at least a part of a preferably endovascular interventional aid with the aid of self-organizing nanorobots consisting of catoms and an associated system are provided. A form of the required interventional aid is determined from at least one 3D image data record of a target region. The determined form is converted to a readable and executable program code for the respective catoms of the nanorobots and is transferred to a storage unit. The program code is executed which prompts self-organization of the previously unstructured catoms to form the required interventional aid according to the previously determined form.

摘要： A system and method for planning and performing a percutaneous medical procedure is described. A three dimensional data set of a patient is registered with respect to a patient position and an interventional apparatus, which may be a C-arm X-ray device. A target within the patient is identified in the image data, and a skin entry point chosen for planning the procedure. The image data set is processed so as to compute a two dimensional fluoroscopic overlay image upon which the target and the skin entry point are displayed. The angulation of the volumetric representation of the C-arm is controlled so as to plan the guiding path for an interventional device, and the planning attempts to achieve one of a bull's eye orientation or a generalized bull's orientation. The interventional device is aligned with the guiding axis to perform the procedure, which may be monitored using X-ray progression views.
