Abstract: In an image post-processing method and apparatus for 3D visualization of 2D/3D fused image data for use in catheter angiography in an endovascular interventional procedure, upon forward movement of a micro-catheter through blood vessel in the interventional procedure, x-ray images are acquired from different projection directions and are subjected to a pattern recognition algorithm for edge-based segmentation of the image regions filled by the micro-catheter, with all remaining image regions being masked out. The segmented projection exposures are prepared by a 3D reconstruction algorithm to obtain an image data set for (pseudo-) three-dimensional representation of the micro-catheter. This image data set are intraoperatively registered and fused with an image data set acquired from an angiographic pre-examination for three-dimensional visualization of the vessel topography. The reconstructed 3D representation of the catheter is mixed into the three-dimensionally prepared representation of endovascular blood vessel sections to be treated.

Abstract: To visually support a catheter ablation in the heart, three-dimensional image data have been used prior to the intervention. During ablation, the position of the catheter is pinpointed by an orientation system. The orientation system acquires electroanatomical 3D mapping data. The two-dimensional image data is assigned to the 3D mapping data in the correct position and dimensions which is a time-consuming step. The invention makes provision for the orientation system being in a fixed location relative to the X-ray system so that a positionally and dimensionally correct alignment of the X-ray image data set with the 3D mapping data is no longer required. An image or surface based 3D-3D alignment of the three-dimensional data acquired prior to the intervention with the three-dimensional X-ray image data is considerably less time-consuming than alignment thereof with the 3D mapping data and is more reliable because more structures is recognized in the three-dimensional X-ray image data.

Abstract: The present invention relates to a device and a method for synchronizing an image capture device with a first image data set. The image capture device is used for recording a second image data set of a periodically moving area or object. Each first image data set contains information as to the point in time, relative to the periodically moving area or object, when recording took place. The device additionally acquires periodically recurring, current information of the area as well as information concerning the recording instant of the first image data set. From the periodically recurring information and the recording instant of the first image data set, a triggering instant is derived which controls at least one recording of the second image data set by the image capture device in such a way that the second image data set contains image data synchronized to the first image data set.

Abstract: An operating method for a polyplanar imaging system for time-resolved imaging of an object is provided. First and second data records are recorded at a fan angle β from different angular positions by a first and second imaging planes arranged at an offset angle γ relative to each other and swiveled through an angle of at least φ=180°+β. A third data record is created by selecting projection images from the first data record beginning from a starting angle α and from the second data record so that the third data record covers an angular range of at least φ. Three-dimensional images are reconstructed based on the third data record. The starting angle α is varied for continuously creating the third data record until α has attained its final value. The contrast of projection images in the third data record or of three-dimensional images is evaluated.
