摘要： The present invention relates to 3D-originated cardiac roadmapping. In order to improve the accuracy of the information provided to the user as navigation information, without any additional burden to the patient such as additional X-ray dose, a method is described comprising the steps of a) providing 3D+t image data of a vascular structure of an object; b) acquiring two-dimensional image data of the object, which object comprises the vascular structure, the 2D image data comprising at least one 2D image; c) projecting the vascular structure, thereby generating a plurality of mask images on the basis of a 3D+t image data; d) registering the at least one 2D image with one of the plurality of the mask images, wherein the registration comprises finding the maximum of a similarity factor between the mask images and the at least one 2D image; e) generating a combination of the at least one 2D image and a projection of the vascular structure on the basis of the 3D+t image data according to the registration; and f) displaying the combination as a guiding vessel tree projection. Thus improved cardiac roadmapping in form of a topographical roadmapping is provided since the roadmapping is based on three-dimensional data.

摘要： According to an exemplary embodiment of the present invention, a cardiac roadmapping technique is provided, that does not rely on the prerequisite of a phase-centric pairing of the angiogram and life images. Instead, both the pairing and accurate registration of the images are combined within a single operation, for example by using a multi-device map. This may provide for robust and precise cardiac roadmapping.

摘要： The present invention relates to a method of filtering an input image using a target oriented filter pattern, which has been obtained by warping a source oriented filter pattern. Such a method comprises a step of computing a source oriented filter pattern at a central image point of said input image, said source oriented filter pattern comprising a source central line, a step of analyzing intensity levels of image points in the vicinity of the central image point for determining a target central line and a step of computing a target oriented filter pattern at the central image point from said target central line and said source oriented filter pattern by defining transformation rules between points of the source and points of the target oriented filter patterns. The method in accordance with the invention finally comprises a step of computing a target oriented filter from said target oriented filter pattern and of applying said target oriented filter to said input image for producing an output image.

摘要： Software System, referred to as Image Transport Engine, for processing a sequence of images by deploying Image Processing Functions onto a multiprocessor system called Platform, which generates input image data in order to provide processed output image data. The Software System comprises a software data partitioning model, referred to as Communication Pattern, which partitions the images of the sequence using time-stamped data packets, the transfer of which may overlap the execution of said image processing functions. The Communication Pattern is formed of Software Modules linked by oriented Connections associated to the Modules through Ports. Each Module activates one Image Processing Function attached to it and manages data transfers and synchronization. The source Module partitions the Input Data into data packets that are Image Strips, formed of consecutive image lines. The Image Strips may overlap other Image Strips. Overlapping Areas formed of extra parts of Image Strips located on either sides of said Image Strips can be processed together with said Image Strips.

摘要： Image processing system for generating a multidimensional adaptive oriented filter to process image data in a number d of dimensions, comprising product means for producing weighted scalar coefficients [W1(r),..,Wi(r),..,Wd(r)] of a number d of vectors of an oriented basis of vectors by a number n of local vectors related to each point; combining means (II) for producing a set of one-scalar weight coefficients [W(r)] from the combination of the weighted scalar products; and filtering means (g) for producing filtered image data [g(x)] from the combination of the image data [I(x)] with the one-scalar weight coefficients [W(r)]. The system further comprises a direction estimator (10) for providing, at each image point, an oriented orthogonal basis of a number d of vectors (e1,..ei,..,ed); a site generator (20) for providing n site vectors of a local vector support; and product means for computing d scalar products of vectors of the orthogonal basis by each of the n site vectors. This system may also comprise means for providing weighting means for the scalar products through scalar functions. The filtering means may comprise a weighted normalized sum of the image data by the one-scalar weight coefficients [W(r)].
