摘要： The present invention relates to an image reconstruction device and a corresponding method for reconstructing a 3D image of an object (7) from projection data of said object (7). In order to obtain 3D images having sharp high-contrast structures and almost no image blur, and in which streak artifacts (and noise in tissue-like regions) are strongly reduced, an image reconstruction device is proposed comprising: a first reconstruction unit (30) for reconstructing a first 3D image of said object (7) using the original projection data, an interpolation unit (31) for calculating interpolated projection data from said original projection data, - a second reconstruction unit (32) for reconstructing a second 3D image of said object (7) using at least the interpolated projection data, a segmentation unit (33) for segmentation of the first or second 3D image into high-contrast and low-contrast areas, a third reconstruction unit (34) for reconstructing a third 3D image from selected areas of said first and said second 3D image, wherein said segmented 3D image is used to select image values from said first 3D image for high-contrast areas and image values from said second 3D image for low-contrast areas.

摘要： The invention relates to an apparatus and a method for the reconstruction of time-dependent cross-sectional images and may be applied for example in perfusion imaging in the vessel system (2) of a patient. According to the method, projections p i j are generated from a number M of different directions d i and at different times t i j . Moreover, the time-dependent intensity function I(x,t) of the reconstructed volume is approximated by a predetermined model function I*( a (x),t), wherein the unknown parameter vector a (x) is estimated for each voxel x. This estimation may be done using the update functions of known reconstruction algorithms like ART for at least N projections p i j in each iteration step.

摘要： The invention relates to an apparatus and a method for the processing of reconstructed 3D images (I) in C-arm based volume imaging which often exhibit spatially slowly varying inhomogeneities caused by inconsistent projection data. To correct the images (I), a retrospective homogenization procedure is proposed. The image (I) is segmented (11, 12) into principal classes like bone, tissue and air based on their gray values. Only the tissue-regions (M) are then used as support in order to fit (14) a spatially slowly varying 2D baseline (B) representing the smooth shape of cupping or other inhomogeneities. Finally the inverse of the estimated 2D baseline is subtracted from the original slice (I) to correct for the inhomogeneities.

摘要： The present invention relates to a method for operating a decision support system (DSS) with a Bayesian Network (BN), the Bayesian Network having conditional probabilities (CP) assigned to each node. There is applied a confidence measure (CM) during use of the decision support system (DSS) on a probability of interest (POI) in a node of interest (NOI), wherein the confidence measure (CM) is a measure for the change of the probability of interest (POI) with respect to a change in one conditional probability (CP_i=x). The invention can quite significantly increase the confidence in the proposed decision of the DSS. The DSS can, indirectly or indirectly, utilise one or more confidence measures (CM) as an input to the proposed decisions or tests to be made by the user; e.g., a clinician considering whether or not to make a certain diagnostic test can be informed of the confidence measure (CM) associated with the diagnostic value of the test as calculated from the BN.
摘要翻译：本发明涉及一种用贝叶斯网络（BN）操作决策支持系统（DSS）的方法，贝叶斯网络具有分配给每个节点的条件概率（CP）。在使用决策支持系统（DSS）期间，对感兴趣节点（NOI）中的感兴趣概率（POI）应用置信度度量（CM），其中置信度度量（CM）是对感兴趣概率（POI）相对于一个条件概率（CP_i = x）的变化。本发明可以显着提高DSS提出的决策的信心。 DSS可以间接或间接地利用一个或多个置信度度量（CM）作为用户提出的决策或测试的输入; 例如考虑是否进行特定诊断测试的临床医生可以被通知与从BN计算出的测试的诊断值相关联的置信度量度（CM）。

摘要： A 3D image of a region of an object is computed from truncated cone beam projection data acquired with an x-ray device and a prior CT image representing a larger region of the object. The truncated projection data are extrapolated to derive pseudoprojection data associated with projection directions outside the detector, and an intermediate CT image is reconstructed based on the truncated projection data completed with the pseudoprojection data. The prior CT image is then registered with the intermediate CT image. Forward projection data associated with projection directions outside the detector are computed from the truncated projection data and the registered prior CT image. The 3D image is finally reconstructed based on the truncated projection data completed with the forward projection data.

摘要： The present invention is directed to a health care data management system comprising a workflow management system and a decision support system, as well as to a corresponding computer program product and a method. The decision support system comprises a probabilistic expert system for medical advice and is arranged to create a query to be sent to the workflow management system. It is also arranged to receive a corresponding answer determined by the workflow management system. This answer comprises entity allocation data relating to the allocation of an entity handled by the workflow management system. Furthermore, the decision support system is arranged to utilize the data as probabilistic input variable(s) for the expert system. Such a system has the advantage of combining up-to-date patient data and organisational data (resource allocation), which is managed by the workflow management system, with the profound medical expertise of a decision support system.
