摘要： In a method for positioning a catheter that has been inserted into a vessel and a device for implementing the method, the road map technique is used, wherein as a mask image, a three-dimensional mask image of the vessel which is composed of number of individual mask images is employed. From these individual mask images, that individual mask image is selected whose exposure direction corresponds optimally to the exposure direction of an instantaneously captured individual image, in order to combine this selected individual mask image with the instantaneously captured mask image and to display the resulting combined image.

摘要： In order to increase the accuracy of the calibration of an imaging system of a radiation treatment system operable to generate a treatment beam, an imaging device generates first data representing a reticle disposed in a beam path of the treatment beam. A first transformation between at least two dimensions of a coordinate system of a radiotherapy device of the radiation treatment system and a two-dimensional (2D) image coordinate system for the imaging device is determined based on the first data. The imaging device generates second data representing a phantom including a plurality of markers. A position of the phantom in the coordinate system of the radiotherapy device is determined based on the second data and the first transformation. A second transformation between three dimensions of the coordinate system of the radiotherapy device and the 2D image coordinate system for the imaging device is determined based on the second data and the determined position of the phantom.

摘要： The invention relates to a method and a device for generating a virtual installation model (2) as an image of a real installation (1). As a database therefor, digital picture data (4) representing pictures of a real installation (1) on the one hand and installation components (13) of a component library (6) on the other hand are used. The data of the installation components as well as the digital picture data (4) of the real installation (1) is evaluated by means of an image analysis (5). Based on this analysis, the identified installation components (13) are assigned to the virtually generated installation model (2). The virtual image of the real installation thus created serves to document the actual structure of the installation/facility, to simplify failure analysis, e.g., in areas that are difficult to access, and/or to operate and monitor the installation/facility. In addition to geometric data, functional data, etc. of the installation components are also stored.
