摘要： The present invention relates to a method and a device for correcting motion in imaging during a medical intervention, by which method a 3D tomographic image of a target area for the intervention is first recorded while there are one or more medical instruments in the target area that will remain there during the intervention. During the intervention 2D fluoroscopic images of the target area are recorded and registered with the 3D image. The registration is therein adjusted for each 2D fluoroscopic image in realtime based in each case on the one or more instruments. The 2D fluoroscopic images are then in each case visualized with representations, concurring in terms of perspective, of the 3D image. Virtually error-free overlaying of the 3D image with in each case one 2D fluoroscopic image can be implemented using the present method and associated device.

摘要： Registration of preoperatively acquired MRI images of soft parts to intraoperatively acquired X-ray images of soft parts is not possible. The invention shows a way of nevertheless using such preoperatively acquired images for superimposition with 2D projections of the soft parts, taking an indirect route via 3D/3D registration of images of the spinal column. For this purpose, 3D image data sets of the spinal column must be obtained separately on the one hand using MRI and on the other using the X-ray imaging system so that the 3D/3D registration produces a mapping rule which then also applies to the preoperatively acquired images of the soft part if the soft part images and the spinal images are acquired without intervening change in the patient position in the MRI scanner.

摘要： The invention relates to a method and a device for the combined representation of a series of 2D fluoroscopic images of the beating heart with a static 3D image data set of the same heart. The fluoroscopic images are registered with the 3D image data set and from this a 2D pseudo-projection on to the image plane of each fluoroscopic image generated in each case. This is then represented with the associated fluoroscopic image overlaid. The method is characterized in that the pseudo-projection is represented differently in each case or is not represented depending on the interval of the cardiac phase of the currently represented fluoroscopic image relative to the cardiac phase of the 3D image data set.

摘要： There is described an analysis method for at least one image data record of an examination object, wherein each image data record features a multiplicity of image data elements. A position in a multidimensional space is assigned to each image data element. Each image data element features an image data value. The image data values of positionally corresponding image data elements of the image data records are specified by means of at least essentially positionally identical regions of the examination object. A computer automatically divides the image data records into empty regions and signal regions, applying an overall assignment rule which is based on the image data values of the image data elements of a plurality of image data records, such that each image data element of each image data record is assigned to either its empty region or its signal region. For each image data record, the computer automatically determines a closed outline which fully contains the signal region of the relevant image data record and, on the basis of the closed outline of the relevant image data record, determines an analysis region such that a further analysis of the relevant image data record can be restricted to its analysis region.

摘要： The present invention relates to a method and to a device for visualizing objects, in particular non-rigid objects. The method and the device are particularly suitable to visualizing three-dimensional objects in the case of medical interventions.The method comprises: providing a three-dimensional image data record of the object, successively taking a series of two-dimensional image data records of the object, individually registering each individual two-dimensional image data record with the three-dimensional image data record, functionally evaluating functional parameters from the successively taken two-dimensional images, extracting two-dimensional projections from the three-dimensional image data record, and superimposing the recorded two-dimensional images with the extracted two-dimensional projections. A clean copy of the abstract that incorporates the above amendments is provided herewith on a separate page.
