摘要： In a method and device for, generating computed tomography images of a periodically moving organ of an organism, the organ having regions with rest phases and movement phases and the rest phases of different regions ensuing at different points in time, an x-ray source is moved around the body of the organism to be examined to generate projections serving for the image generation during at least one rotation of the x-ray source around the subject to be examined and during a duration that is at least equal to a period of the motion. The projection data are analyzed as to whether the data were acquired during a rest phase or movement phase of a respective region of interest of the organ, and an image of the organ is reconstructed using only data acquired during a rest phase of a respective region of interest of the organ.

摘要： The invention is directed to a method and a device for separate three-dimensional presentation of arteries and/or veins of a vessel system in a part of the body of a vertebrate by a rotation computer tomography. A masking run of the tomograph is undertaken without contrast media around the part of the body. Then two filling runs with contrast media are executed, with the venous phase of vessel contrasting during the first filling run occurring during the arterial phase of vessel contrasting of the second filling run and vice-versa. The data from the first and second filling run is combined into data sets from the arterial or the venous phases of the vessel contrasting of the filling runs. The data of the masking run is subtracted from the combined data sets to obtain final data sets for a three-dimensional presentation of the arterial or the venous vessel system.

摘要： The present invention relates to a method and a device for recording X-ray images by means of a robotically controlled C-arm system which includes an image recording system (9, 10) that can be rotated in a recording plane around a turning center (17) by means of a C-arm (7) and with which, through rotating of the C-arm (7), a plurality of radioscopic images of a region (14) of interest in an object (13) positioned on an object positioning facility (15) are recorded at different rotation angles, from which images one or more cross-sectional images or a three-dimensional image of a region (14) in the object can be reconstructed. With the method, the C-arm (7) is compliantly repositioned in a collision-free manner in synchronism with the rotation such that the region (14) of interest in an object will, at least at each rotation angle at which image recording takes place, be located within a cone beam (16) of an X-ray bundle of the image recording system (9, 10). The method and associated robotically controlled recording device thus enable the three-dimensional image reconstruction also of regions located at the edge of the object's longitudinal center line.

摘要： An x-ray system features a control device (6), a data storage device (12) and two x-ray units. Each x-ray unit features an x-ray source (1,3) and an x-ray detector (2,4) which can be pivoted around a pivot axis (5) and are arranged opposite one another in relation to the pivot axis (5) in each case. An object (10) can be arranged in the area of the pivot axis (5). The control device (6) controls the x-ray units so that they are simultaneously pivoted by the pivot angle (δα,δβ) around the pivot axis (5). In this case images of the object (10) are recorded by means of the x-ray detectors (2,4) at angular positions (αi,βj) and conveyed to the data storage device (12). The pivot angle (δα,δβ) and the angular positions (αi,βj) are determined here such that, on the basis of the recorded images of the object (10), at least one 3D reconstruction of the object (10) can be determined which also occurs afterwards.
