摘要： An interactive user assistant for imaging processes analyzes medical image data pertaining to regions of interest. The user assistant compares displayed medical images and/or the data underlying the medical images with expected medical image data. The user assistant identifies whether or not the displayed medical image meets expectations or is plausible. The user assistant may use previously analyzed data in determining whether the displayed medical image is as expected. If the displayed medical image does not meet expectations, the user assistant determines whether or not the cause of the disagreement between the displayed and expected images is ascertainable. If the cause of the disparity between the images is ascertainable, the user assistant presents specific recommendations. If the cause of the disparity between the images is not ascertainable, the user assistant presents general suggestions.

摘要： A method and an apparatus are disclosed for visualizing deposits in blood vessels, particularly in coronary vessels. In such a method, 2D slice images may be reconstructed from the measurement data, with image data of the 2D slice images being post-processed for local determination of brightness values and/or of default values on which these are based in the 2D slice images. In the presentation of the 2D slice images, one or more image areas are marked in which, in the post-processing, pixels are automatically color-coded and presented according to a predeterminable transfer function which assigns different colors to different value ranges of brightness values and/or of default values on which these are based.

摘要： At least one embodiment of the present invention relates to a method and/or an apparatus for determining the spatial profile of a vessel axis in volume data records for medical imaging, in particular for producing slice images of vessels which are obtained by curved planar reformation CPR and can be rotated freely. In at least one embodiment of the method, the vessel axis is marked interactively on the displayed MPR or MIP images by marking points using a two-dimensional coordinate system. Depth information is derived automatically for each marking point from the known position of the respective image in the stack or using the known calculation procedure for MIP images, and the marking points are extended in dimension on the basis of the depth information in order to obtain extended marking points using a three-dimensional coordinate system. The three-dimensional profile of the vessel axis, which is used for producing CPR images which can be rotated freely, is then obtained by linking the extended marking points. The method makes it possible, in at least one embodiment, to determine the profile of the vessel axis with less time and computation effort.
