摘要： A method of aligning a pair of images with (101) a first image and a second image, wherein said images comprise a plurality of intensities corresponding to a domain of points in a D-dimensional space includes identifying (102) feature points on both images using the same criteria, computing (103) a feature vector for each feature point, measuring a feature dissimilarity (104) for each pair of feature vectors, wherein a first feature vector of each pair is associated with a first feature point on the first image, and a second feature vector of each pair is associated with a second feature point on the second image. A correspondence mapping (105) for each pair of feature points is determined using the feature dissimilarity associated with each feature point pair, and an image transformation (106) is defined to align (108) the second image with the first image using one or more pairs of feature points that are least dissimilar.

摘要： A method and apparatus for three dimensional (3D) computerized tomographic (CT) imaging of a region-of-interest (ROI) in an object, wherein image reconstruction processing is applied to a plurality of sets of pixels of 2D image data, each set being acquired on a pixelated 2D detector. The image reconstruction processing comprises filtering each of the acquired 2D image data sets for developing a corresponding plurality of filtered 2D images; and then 3D backprojecting the filtered 2D images into a common 3D space, thereby reconstructing in the 3D space a 3D image of the ROI in the object. In the present invention the filtering step comprises dividing the pixels of each set of the acquired 2D image data sets into first and second groups, and separately filtering the image data of each group to develop for each group it's own contribution to the corresponding filtered 2D image. In accordance with one embodiment of the invention, the first group essentially comprises those pixels that contribute to a given filtered 2D image in a space-invariant manner, and the second group essentially comprises those pixels that contribute to the given filtered 2D image in a space-variant manner. In accordance with another embodiment of the invention, the first group essentially comprises a contiguous portion of the pixels of each set that are entirely internal to the boundaries of a data combination mask that is applied to each set of the acquired 2D image data, and the second group essentially comprises at least one boundary region of contiguous pixels that are on or adjacent to a data combination mask boundary.

摘要： A two-step 3D Radon inversion processor for processing Radon data on a set of vertically oriented co-axial .phi.-planes that partition Radon space, wherein each of the .phi.-planes is sampled during the processing so as to have its own independent local Radon origin. In accordance with further principles of the present invention, a 3D Radon data generator generates Radon data on a set of vertically oriented co-axial .phi.-planes that partition Radon space, wherein each of the .phi.-planes is sampled so as to have its own independent local Radon origin, and a two-step 3D Radon inversion processor independently processes each of the .phi.-planes. Any shift of the local Radon origins with respect to a global coordinate system is compensated for during the 3D Radon inversion processing. Compensation for the origin shift may be made during or after a first step of the Radon inversion processing.

摘要： A scanning and data acquisition technique for three dimensional (3D) computerized tomographic (CT) imaging of an object, wherein scanning at a plurality of positions along a source scanning trajectory causes an area detector to acquire cone beam projection data corresponding to a shadow of said object at each of scanning positions and Radon derivative data is calculated by processing line integral values from cone beam projection data. In order to improve the calculation efficiency of the Radon derivative calculation, calculation of the Radon derivative data uses a determination of the left and right boundaries of the shadow for each of the scanning positions, and calculates the Radon derivative data only using projection data from within the determined boundaries.

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.
