Abstract: A method and an arrangement are disclosed for displaying time variable processes in medical imaging. In the case of the method, 2D or 3D image data obtained from an imaging modality are processed in order to produce a temporal sequence of images. Intermediate images that are displayed in temporal sequence with the images are generated by interpolation between temporally consecutive images. The processing of the 2D or 3D image data is performed, from which the images are transmitted to a display unit, in which the interpolation is carried out and which displays the images with the intermediate images. The present method and the associated arrangement permit a fluid display of the time variable processes on the display screen.

Abstract: salient An apparatus is disclosed for automatically detecting salient features in medical image data. The apparatus includes a memory device for storing the image data, at least one determination module for determining one or more anatomical regions which are acquired by the image data, a number of different examination modules that respectively include an application for automatically detecting specific salient features in a specific anatomical region, an input unit via which a primary application can be started, a control unit that on the basis of the anatomical regions determined by the determination module automatically selects and executes in the background further applications, as well as an output unit on which the result of the primary application is displayed together with an item of information relating to additional salient features that have been detected automatically with the aid of the applications executed in the background.

Abstract: In a method for image generation with an imaging modality, in particular a computed tomography system, in which measurement data for a sequence of 2D slice images of a subject volume are acquired with the imaging modality, image data for the 2D slice images are reconstructed from the measurement data and the image data are post-processed for generation and display of one or more secondary images, the post-processing and display is begun on the basis of already-reconstructed image data before all image data are completely reconstructed for the 2D slice images. The image data are initially reconstructed with a larger slice separation and are subsequently completed in a by a reconstruction of the entire subject volume with image data of remaining intermediate images, such that the representation of the one or more secondary images is completed by the post-processing of the image data of the intermediate images over time.

Abstract: A method is disclosed for automatically determining the rectum distance in a patient's colon, the path in the colon between a selected site, preferably a lesion, and the rectum being determined by processing 3D image data records. At least two 3D image data records are recorded with the patient being differently positioned. Further, the path between the rectum and selected site is determined from the common perusal of the at least two 3D image data records.

Abstract: Disclosed is an automated technique for analyzing the affected region due to an embolism in an organ. A segmented image of the organ vasculature is generated using image volume data received, for example, from a Computed Tomography (CT) machine. An embolus is then identified (either manually or automatically) within the segmented image, and the volume of the organ affected by the embolism is automatically determined. The volume of the organ affected by the embolism may be determined by computing a sub-tree within the segmented image, where the sub-tree comprises vessels that are distal to the identified embolus point. In one embodiment, the sub-tree is generated by determining a plane perpendicular to a vessel at the embolus point such that the sub-tree comprises a distal portion of the vasculature with respect to the plane. Unwanted overlapping trees are identified (e.g., by analyzing branch angles) and removed from the sub-tree.

Abstract: In a tomography-capable imaging examination apparatus, and an operating method therefor, an operator first determines a desired scan volume of the examination subject, and then, controlled by the computer device, a raw data set, having data allocated to different directions, is acquired in the scan volume. For planning the subsequent calculation of the resulting image—keeping pace with the scan or immediately after its termination—the computer device calculates and displays a graphic overview representation of the subject of examination from the raw data. The overview representation contains three-dimensional information about the scan volume. In this volume, the operator selects a diagnostically relevant region of representation. Using an image calculation algorithm, the computer device calculates a diagnostically relevant resulting image in the selected region of representation. The quantity of data thus is reduced immediately upon its origination.

Abstract: In an x-ray computed tomography apparatus, and an operating method therefor, a data set containing patient-specific values is provided, a computer program to operate the x-ray computed tomography apparatus is provided, wherein parameters are assigned predetermined value, and the patient-specific values are adopted by the computer program, associated with the parameters corresponding thereto, and the predetermined values are overwritten with the patient-specific values.
