    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.

For the method, 3D image data of at least the heart, which is captured using a tomographic 3D imaging method prior to execution of the catheter application, and electroanatomical 3D mapping data of at least one area of the heart to be treated, which is captured during execution of the catheter application, is provided and the electroanatomical 3D mapping data and/or at least part of the 3D image data is displayed during execution of the catheter application. The method is characterized in that, in the electroanatomical 3D mapping data and/or the 3D image data, the contour of one or more areas (3) relevant to the catheter application is captured and transferred to the other system in each case on which the areas (3) are superimposed as a single polyline (5) in the representation (2, 4) of the electroanatomical 3D mapping data and/or 3D image data. The method proposed and the associated apparatus provide the user with a rapid overview of the areas relevant to the catheter application.

    摘要: In a method for mathematical compensation of a periodic movement of an organ in a first image-generation method used to image said organ, two time series of three-dimensional image data are acquired using gating, one by the first image-generation method and one by the second image-generation method, the image data that have been acquired by the second image-generation method being used to calculate motion fields which are applied for the compensation of the data from the time series which was acquired by the first image-generation method. The compensation encompasses the mathematical inclusion of motion fields and the mapping of the image data to a reference time. All the image data mapped back to the reference time are added together.

    摘要: The present invention relates to a method for imaging using an image-generating, endoluminal instrument (1) by means of which a sequence of 2D image data of a hollow channel (2), in particular a vessel, of an object under investigation is recorded, wherein the images are recorded in a known temporal relation to a periodic movement of the object under investigation and spatial coordinates of the image are captured by means of a position sensor during each recording of an image (5) and stored as position data (9, 10) together with the 2D image data of the image (5). The method is characterized in that first position data (10) which does not lie in a predefinable movement phase of the object under investigation is corrected, before or after being stored, by interpolation between second position data (9) which does lie in the specified movement phase and/or by subtraction or addition of predetermined values. By means of the method a movement correction of the data can be performed without the need to reduce the volume of recorded image material.

    摘要: The device according to the invention ensures accurate and in particular sensitive navigation of the probe, which can be inserted into a body, despite the fact that the remote control uses simple means, by means of a movement (MR;MB;MP) corresponding intuitively to the navigation of a probe using the control device (1). Intuitive operation can be converted in particular using an inventive U-shaped embodiment of the control device (1). Sensitive controllability can be increased by transmitting the mechanical interaction between the probe and an environment under examination to the control device (1) and thus directly to the operating hand (3) by means of inventive feedback.
