摘要： A method is disclosed for the reduction of image artifacts, in particular metal artifacts, during the generation of computed tomography image data of an object. In at least one embodiment of the method, two CT image data sets are generated with different medium x-ray energies. By way of a weighted combination of the two CT image data sets, a new image data set is calculated. The weighting factor employed in the weighted combination is here selected in such a way that the image artifacts in the new CT image data set are significantly reduced compared with the image artifacts in the two original CT image data sets. In this way it is possible in a simple manner significantly to reduce in particular metal artifacts in CT images.

摘要： A method and a correspondingly configured tomography scanner are disclosed for normalizing image data with respect to a contrast in the image data produced by a contrast agent, the image data illustrating a tissue structure to be examined and at least part of a blood vessel system of an examination region connected to the tissue structure, which are at least in part permeated by the contrast agent. In an embodiment of the method, image data of the examination region is provided with the aid of the tomography scanner. At least one section of a reference vessel permeated by contrast agent is selected in the image data. The image data is normalized on the basis of image data from the section of the reference vessel such that the contrast in the image data as a result of the contrast agent is almost independent of patient-specific and examination-specific parameters in order to ensure that image data from different times can be compared.

摘要： At least one embodiment of the present application relates to a method and/or a device for automatically detecting chemical anomalies and/or salient features in soft tissue of an object area. In at least one embodiment of the method, two image data records of two computed tomography pictures of the object are provided which are recorded in the context of a different spectral distribution of the X-radiation. The following steps are carried out for each voxel of at least one interesting slice whose X-ray attenuation values are characteristic of soft tissue. Firstly, two X-ray attenuation values of the voxel, or two averaged X-ray attenuation values of the environment of the voxel are used to determine a data point of the voxel in a diagram in which the X-ray attenuation values are plotted against one another in the context of the two spectral distributions of the X-radiation. A perpendicular distance of the data point from a connecting straight line that connects prescribed data points for pure fat and for pure soft tissue in the diagram is then calculated. Finally, the voxel is marked and displayed with highlighting when its distance exceeds a prescribed threshold value for the distance. In at least one embodiment, at least one of the proposed method and the associated device enable chemical anomalies to be automatically detected on the basis of computed tomography.

摘要： The invention relates to a plug-in combination of appliances for protecting against overvoltages, said combination of appliances comprising: a socket-type lower part and at least one plug-in module, which can both receive overvoltage protection elements; contact elements and contact counter elements that are respectively arranged in the lower part and in the plug-in module; and complementary guide rails or guide grooves for inserting or pushing-on and fixing the respective plug-in module. According to the invention, functionally separated, mechanical catch or snap-in elements act between the respective plug-in module and the socket-type lower part independently of the forces which hold together the contact elements and the contact counter elements in a positively fixed and/or non-positively fixed manner when the plug-in module is in use. The catch or snap-in function can be cancelled without any mechanical auxiliary means when the respective plug-in module is to be replaced.

摘要： A method and a CT system are disclosed having a computation unit for distinguishing between four materials (M1, M2, M3, M4) in tomographic records of a dual-energy CT system, wherein the size of a two-dimensional or three-dimensional viewing area is defined around each voxel whose material content is to be distinguished. In an embodiment of the method, the adjacent voxels from the viewing area on an HU value diagram are imaged for each voxel (Vi) whose material content is to be distinguished, the distances from the diagonals are calculated for all the imaged voxels, and the mean squares of these distances are formed (x12, x22). If the mean square distance (x12, x22) to one diagonal is less than to the other diagonal, then the composition of the voxel is assumed to be composed of the materials to whose diagonal the lower mean square distance (x12, x22) occurs.
