摘要： The invention relates to a method and a device for the iterative reconstruction of cross-sectional images of the heart (7) of a patient based on projections (P1, . . . P5) from different directions which are for example generated with a helical cone-beam CT scanner. A cardiac weight function (f) quantifies how near the projections (P1, . . . ) are to a given observation phase (To) of the heart cycle based on simultaneously recorded electrocardiographic signals (ECG). The whole set of projections (P1, . . . ) is divided into subsets (S1, . . . ) which each contain only projections corresponding to a similar cardiac weight (f), and an iterative reconstruction algorithm like ART uses in one update or iteration step all projections of such a subset (S1, . . . ) simultaneously.

摘要： The present invention relates to an imaging system for imaging a field of interest, in particular to a computed tomography system. The imaging system comprises an irradiation unit (2) which moves relative to a field of interest along a first trajectory (501) and along a second trajectory (503). While the irradiation unit (2) moves along the first trajectory (501), first detection data are acquired and, while the irradiation unit (2) moves along the second trajectory (503), second detection data are acquired. An intermediate image of the field of interest is reconstructed from at least the second detection data, and virtual detection data are determined by forward projection through the intermediate image. Finally, an image of the field of interest is reconstructed from the first detection data and the virtual detection data.

摘要： The invention relates to a computerized tomography method, in which an examination area is scanned radiographically along a helical trajectory by a conical beam. The radiation transmitted through the examination area is measured by means of a detector unit, wherein the absorption distribution in the examination area is reconstructed exactly or at least quasi-exactly from these measured values. Reconstruction uses redundant measured values and comprises derivation of the measured values from parallel rays of different projections, integration of these values along κ-lines, weighting of these values and back-projection.
