    Abstract: Systems and methods are provided for registering maps with images, involving segmentation of three-dimensional images and registration of images with an electro-anatomical map using physiological or functional information in the maps and the images, rather than using only location information. A typical application of the invention involves registration of an electro-anatomical map of the heart with a preacquired or real-time three-dimensional image. Features such as scar tissue in the heart, which typically exhibits lower voltage than healthy tissue in the electro-anatomical map, can be localized and accurately delineated on the three-dimensional image and map.

    Abstract: A computer-implemented method for image registration includes accepting a three-dimensional (3-D) image of an organ. The image includes a first plurality of image points with respective image coordinates. A map defining a distribution of values of a physiological parameter over the organ is accepted. The map includes a second plurality of map points with respective map coordinates. Confidence levels are associated with one or more of the map coordinates and image coordinates. Weights are assigned to at least some of the map points and image points responsively to the confidence levels of the respective map coordinates and image coordinates. The 3-D image is fitted with the map by calculating a geometrical transformation between the map coordinates and the image coordinates based on the weights.

    Abstract: A method and a device for obtaining a volume data set of a mobile tissue or organ of a patient by a C-arm X-ray device are provided. An electromagnetic sensor of a position detection system is arranged indirectly on the tissue or organ. The X-ray device obtains a plurality of X-ray projections from the tissue or organ from various projection directions. A first method consists of reconstructing a volume data set from the X-ray projections, in which the electromagnetic sensor adopts a position characterizing a displacement phase of the tissue or organ. A second method consists of reconstructing a volume data set from the X-ray projections captured when the electromagnetic sensor was located in a position characterizing a displacement phase of the tissue or organ. A third method does not capture an X-ray projection for the reconstruction if the electromagnetic sensor is located in a position characterizing a displacement phase.

    Abstract: 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 visualised 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 visualised, 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.
