    摘要: System and method for enabling intra-operative selection of an image registration transformation for use in displaying a first image dataset and a second image dataset in correspondence with one another. Image dataset acquisition devices (12, 14) obtain the first and second image datasets. A similarity function indicative of a likelihood that the first and second image datasets are in correspondence with one another is computed by a processor (16) and then a ranking of each of a plurality of local maxima of the similarity function is determined. Registration transformations derived from a plurality of the local maxima are displayed on a display (18), and using a user-interface (22), a physician can select each registration transformation to ascertain visually whether it is the clinically-optimal registration transformation for subsequent use.

    摘要: The present invention relates to visualizing information of an object. In order to provide spatial information and in addition situation specific data to the user while ensuring an effective perceptibility, a method (110) is provided comprising the steps of: a) providing (112) pre-navigation data (114) of a region of interest of an object (22); wherein the pre-navigation data comprises spatial geometrical data (116) and a functional parameter surface (118) in correspondence to the spatial geometrical data; b) acquiring (120) live image data (122) of the region of interest; c) detecting (124) an element (126) in the live image data; d) determining (128) spatial relation (130) of the pre-navigation data and the live image data; e) determining (132)the position (134) of the detected element in the spatial geometrical data, which determining is based on the spatial relation, and computing (136) a predetermined related point of location (138) on the functional parameter surface; f) generating (140) a combination (142) of a simplified surface representation (144) of the region of interest, which simplified surface representation is based on a visualization of the functional parameter surface, and a marker (146) indicating the computed predetermined related point of location; and g) displaying (148) the combination as navigation guidance (150).

    摘要: A method for identifying a structure in a volume of interest is provided. The method comprises acquiring a plurality of points related to the structure in a continuous mode, and subsequently registering at least one of the points to a previously acquired imaging dataset of the structure. An apparatus, system and a computer-readable medium are also provided. The present invention provides faster acquisition of EAM points by modifying the mapping system so that catheter tip locations are automatically and continuously recorded without requiring explicit navigation to and annotation of fiducial landmarks on the endocardium.
