摘要： 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. The evaluation of the data can be accelerated, and a prospective quality control can be carried out.

摘要： 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.

摘要： A method and a device are disclosed for visualizing a sequence of tomographic image data records of an examination volume that has been recorded at a time interval from one another. In at least one embodiment of the method, the image data records are firstly registered with one another. On the basis of the registration with regard to a display perspective and a displayed volume region identical views are generated from at least three of the image data records and displayed on an imaging surface of a graphic display unit in a fashion superposed on one another with adjustable. weighting and/or adjustable transparency. For the superposed display, there are inserted on the imaging surface one or more controllers by whose interactive operation an operator can adjust or vary the weighting and/or transparency with which the at least three views are superposed. The present method and the associated device, in at least one embodiment, allow an operator to evaluate the corresponding image data records with a reduced outlay on time.

摘要： A method is disclosed for post-processing of a 3D image data record which has been recorded by way of an imaging tomographic appliance of a body area, and covers at least one hollow organ which is at least partially filled with contrast agent. An imaging apparatus is also disclosed. In the method, an automatic three-dimensional edge detection process is carried out in the 3D image data record in order to determine transitions between areas which have contrast agent and a wall of the hollow organ as boundary surfaces. A weighted high-pass filtering process is carried out at right angles to the boundary surfaces and leads to removal of the areas which have contrast agent and in which process areas around the transitions are given a lower weighting than areas which are further away from the transitions. After low-pass filtering in the areas around the transitions, a 3D image data record is produced from which the areas which are filled with contrast agent are eliminated, without image artifacts being produced at the transitions to the wall of the hollow organ. The method can be used in particular for virtual bowel cleaning in virtual colonography.

摘要： 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. The volume of the organ affected by the embolism is determined by calculating a volume of the organ that is perfused by the sub-tree. The affected volume may be adjusted by scaling the volume based on the percentage occlusion of the partial embolus.
