摘要： In a method for automatically determining coordinates, relative to a reference coordinate system, of markers contained in a 3D volume data set of a subject provided with markers imaged in 2D projections of the 3D volume data set are detected, the centers of gravity of the imaged markers are determined, and back projection straight lines through the markers are established. The intersection points of the back projection straight lines with each other are identified, or the points with the smallest distance from one another on different back projection straight lines are determined if the back projection lines arc skewed. Spatially limited areas are identified, which contain an accumulation of intersection points of back projection straight lines or an accumulation of points with the smallest distance from one another. The coordinates of the centers of gravity of these spatially limited areas are calculated and are used as the coordinates for the respective markers.

摘要： The invention relates to a device and to a method for visual assistance during the electrophysiological use of a catheter in the heart, enabling electroanatomic 3D mapping data relating to an area of the heart to be treated to be visualized during the use of the catheter. Before the catheter is used, 3D image data of a body region containing the area to be treated is detected by means of a method for tomographic 3D imaging. The area to be treated or significant parts thereof are extracted from said 3D image data, in order to obtain selected 3D image data. The electroanatomic 3D mapping data and the selected 3D image data obtained are then classed in terms of position and dimension, and are adjacently visualized, for example, during the catheter ablation. The inventive method and associated device enable the orientation of the operator to be improved during the use of a catheter in the heart.

摘要： The invention relates to a method and a device for visually supporting an electrophysiology catheter application in the heart, whereby electroanatomical 3D mapping data of an area of the heart to be treated which are provided during performance of the catheter application are visualized. Before the catheter application is carried out, 3D image data of the area to be treated are recorded by means of a tomographical 3D imaging method, a 3D surface profile of objects in the area to be treated is extracted from the 3D image data by segmentation and the electroanatomical 3D mapping data provided and the 3D images representing the 3D surface profile are associated with each other in the correct position and dimension relative each other and e.g. visualized in an superimposed manner during the catheter application. The present method and the corresponding device allow for an improved orientation of the user who carries out an electrophysiology catheter application in the heart.

摘要： A system and method of treating tachycardias and similar syndromes by the use of catheter ablation of tissue is described. A computed tomography (CT)-like image of the heart is obtained and processed to segment the various types of tissue. Papillary muscle areas are identified and displayed differently from the other nearby tissues so that the muscles can be avoided during treatment to avoid or minimize damage to the muscles during ablation treatment. Electrophysical data and scar tissue may also be identified in the image, which may be of the endoscopic type. The position of the catheter may be displayed as a synthetic image on the endoscopic view.
