    Abstract: 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.

    Abstract: 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.
