摘要： The invention relates to a method of processing cardiac data. The method comprises the steps of modeling a patient-specific coronary-artery anatomy, modeling a surface geometry of the patient-specific myocardium at a heart division, projecting the coronary-artery anatomy and the myocardium surface geometry onto a plane which is transverse with respect to an axis of the heart division, dividing the projected myocardium surface geometry in arterial territories being closest to a corresponding coronary-artery, and representing cardiac data associated with a specific arterial territory by a reduced number of cardiac parameters derived from said cardiac data.

摘要： An apparatus 1000 includes an input 1010 for receiving an N-dimensional signal, N≥2. A storage 1030 stores a composite model of a composite structure for estimating parameters of the model with respect to the signal. The composite model is based on constituent models 210-290 that each correspond to a constituent structure in the signal and that are incorporated in the composite structure. Each constituent model is designated for estimating parameters of the constituent model with respect to the signal based on prior knowledge of the constituent structure. At least two of the constituent models are based on differing technologies. Each constituent model is provided with a uniform interface for controlling the constituent model and for retrieving parameters estimated by it. A processor 1020 is programmed to estimate the model parameters by controlling the constituent models to estimate their parameters; to retrieve estimated parameters from the constituent models; and to estimate parameters of the model in dependence on the retrieved parameters.

摘要： The invention relates to a system (100) for delineating a first object in image data by using a model, the first object describing a first anatomical structure, the system comprising an adaptation unit (120) for adapting the model to the image data, thereby delineating the first object, wherein an aspect of the adaptation depends at least on a second object previously identified in the image data, the second object describing a second anatomical structure. Thus, the system (100) of the invention is arranged for adapting the model to the image data, based on the energy functional of the model, where energy terms describing forces acting on the model or on the model parts, model details, and adaptation algorithms are allowed to be dependent on the position of the second object. Hence, the system (100) is capable of using further information available in the image data, which information may be derived from the previously identified second object comprised in the image data.

摘要： A system for visualizing a 3D volume, in particular for medical applications, includes an input 1010 for receiving a three-dimensional set of data representing voxel values of the 3D volume. The data set is stored in a storage 1030. A processor projects the volume onto an imaginary 2D projection screen from a predetermined viewpoint. For each pixel of the 2D projection image a ray is cast through the pixel and through the volume. A protocol is used that, while traversing along ray positions within the volume, determines a rendering algorithm and/or rendering parameters in dependence on the ray position. For each ray position the determined rendering algorithm/parameters are used to calculate a contribution to a pixel value of the pixel based on at least one voxel value within a predetermined range of the ray position. An output 1040 is used for providing pixel values of a 2D image for rendering on a display.

摘要： A method of creating a segmentation of a volume of interest in an object data set is described, which object data set is formatted into object data slices, in which at least two object data slices each contain a contour line defining the portion of the volume of interest present in that object data slice as a region of interest. The method comprises the steps of calculating at least one surface which cuts through each of the at least two regions of interest, defining two curves on each of said surface which intersect with the contour lines, arranging for those curves to define the portion of the volume of interest present in said surface, calculating on each of the remaining object data slices a contour line which includes those points on the curves which intersect with that object data slice. A computer program and work station are also described.

摘要： The apparatus (40) arranged for enabling an object mapping in a multidimensional dataset has an input (42) for receiving the multi-dimensional dataset in any suitable form. The core of the apparatus is formed by a processor (44), such as a conventional microprocessor or signal processor, a background storage (48) (typically based on a hard disk) and working memory (46) (typically based on RAM). The background storage (48) can be used for storing the dataset (or parts of it) when not being processed, and for storing operations of the graphic relational application macro and models (when not being executed by the processor). The main memory (46) typically holds the (parts of) the dataset being processed and the instructions of the graphic relational application macro and the models used for processing those parts of the dataset. The apparatus (40) according to the invention comprises computation means (45) arranged to define a set of geometric relations between a set of geometric templates using a geometrical relational application framework macro and means (47) for associating the multi-dimensional graphic objects with the geometric templates. Preferably, means (45) and (47) are operable by a computer program (43), preferably stored in memory (48). An output (49) is used for outputting the result of the mapping. Preferably, the output comprises a result of the associating of the multi-dimensional graphic objects with the geometric templates inter-related by the graphic relational application macro. The invention further relates to a method, a computer program, an image analysis system and an imaging system for an object mapping in a multi-dimensional dataset.

摘要： The invention refers to a method of producing a medical report comprising a dynamic image information based on a volumetric scan of one or more internal organs of a subject. According to the method two-dimensional images for simulating a three-dimensional view of the one or more internal organs based on the volumetric scan are calculated using a workstation. The resulting two-dimensional images are next projected on a surface of a geometrical object, which is then unfolded to a two-dimensional flat plane (U,L,F,R,B,D), and stored in a generated textual medical report for further analysis on a low0end computer. Advantageously the stored two-dimensional images are displayed dynamically within the medical report, either as a sequence of images or as a part of a virtual environment.

摘要： The invention relates to the processing of a series of images. A multi-dimensional data set is formed from the series of images, for example, by stacking the images in order of succession. A cut plane is taken through the stack, that is, in the direction of succession and a slice through the stack is taken along the cut plane. A region of interest is derived from the slice. The invention is particularly useful for cardiology where a stack of successive MR images of a moving heart is formed. The ventricles of the heart are accurately segmented while using the slice in the direction of the time axis.
