摘要： A method is disclosed for scanning a cyclically moved examination object using a contrast agent within the scope of a preliminary examination by way of a CT scanner, in which measurement data is recorded at a sequence of recording times. A first image is reconstructed at every recording time from the measurement data, from which a time profile of a concentration of the contrast agent is established. The recording times for respectively recording a certain phase of the motion are synchronized with a motion signal from the examination object. A second image with a time offset with respect to the first image is reconstructed from the measurement data at each recording time. A motion curve representing a time profile of an intensity of the cyclical motion is established by comparing the first image and the second image at each recording time.

摘要： A method is disclosed for scanning a cyclically moved examination object using a contrast agent within the scope of a preliminary examination by way of a CT scanner, in which measurement data is recorded at a sequence of recording times, and in which a first image is reconstructed at every recording time from the measurement data, from which a time profile of a concentration of the contrast agent is established. In at least one embodiment, the recording times for respectively recording a certain phase of the motion are synchronized with a motion signal from the examination object, wherein a second image with a small time offset with respect to the first image is reconstructed from the measurement data at each recording time, and wherein a motion curve representing a time profile of an intensity of the cyclical motion is established by comparing the first image and the second image at each recording time. As such, motion information can also be obtained from the mandatory preliminary examination with a minimally increased dose. A corresponding CT scanner and a computer program are also disclosed.

摘要： In a method for operating a computed tomography apparatus, a topogram of a region of a subject, for which a volume dataset is to be obtained by computed tomography, is obtained and the image data of the topogram are analyzed to obtain an analysis result. The analysis result can be used for mixing a marking into the topogram for defining the region for which the volume dataset is to be obtained, or the analysis result can be used to align and operate a gantry of the computed tomography apparatus for obtaining the volume dataset. Manual determination and entry of the marking and/or manual control of the gantry, are thus avoided.

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.
