摘要： In an x-ray computed tomography apparatus and a method for conducting test measurements therein, a combined phantom is employed that is formed of several individual phantoms, each forming a segment of the combined phantom, and the combined phantom is affixed to a platform of the computed tomography apparatus that is movable with respect to an x-ray data acquisition unit of the computed tomography apparatus. The platform is moved into a first position and a first x-ray absorption distribution of a first segment of the combined phantom is obtained, and the platform is moved into a second position and a second x-ray absorption distribution is obtained of a second segment of the phantom. Movement of the platform and operation of the data acquisition unit for obtaining the first and second x-ray distributions are automatically controlled by a computer program.

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： In a computed tomography apparatus with a detector array whose output signals are processed into shadowgrams in a computer, for which purpose a relative displacement ensues between the measuring unit composed of x-ray source and a detector array and the patient support in the longitudinal direction of the support, the output signals are acquired by the computer. A convolution of the output signals ensues in the longitudinal support direction (Z-direction) during the scanning, with values extrapolated from measured values also being used in the calculation. A lagging of the shadowgram presented on the monitor compared to the measuring unit is thus avoided.

摘要： A method is for medical imaging and image processing in the form of a perspective volumetric display. The method includes providing a multiplicity of temporally graded 3D data volumes at a multiplicity of instants, a 3D data volume, respectively being assigned to an instant; and prescribing a spatially absolutely fixed viewer position within an evaluation volume for at least one 3D data volume at a first instant. The method further includes determining a temporal correlation between the spatially absolutely fixed viewer position and the evaluation volume for at least one further 3D data volume at at least one second instant; determining a viewer position, spatially relatively fixed in relation to the evaluation volume, within the evaluation volume for the at least one further 3D data volume at the at least one second instant; and displaying the interior of the evaluation volume from a perspective of the spatially relatively fixed viewer position for the at least one further 3D data volume at the at least one second instant.
