摘要： A method and apparatus are provided to improve CT image acquisition using a displaced acquisition geometry. A CT apparatus may be used having a source (102) and a detector (104) transversely displaced from a center (114) of a field of view (118) during acquisition of the projection data. The amount of transverse displacement may be determined based on the size of the object (108). The source and the detector may be adjusted to vary the size of the transverse field of view. The first data set acquired by the detector may be reconstructed and used to simulate missing projection data that could not be acquired by the detector at each projection angle. The measured projection data and the simulated projection data may be used to obtain a second data set. The second data set may be compared to the first data set to produce a corrected data set.

摘要： A method for providing a displayable pixel data set (11) from measurement data (3) provided by a differential phase-contrast X-ray imaging system (1) and a device (7) adapted to perform such method are proposed. The measurement data (3) comprise three types of measurement information: an absorption representing image data set A, a differential phase-contrast representing image data set D and a coherence representing image data set C. Each of the image data sets A, D and C comprises a 2-dimensional or 3-dimensional set of pixels (5) and the three image data sets are spatially aligned with each other. In the method for providing a displayable pixel data set, a colour value corresponding to a position in a 3- dimensional colour space (9) is attributed to each pixel (13) in the displayable pixel data set (11), wherein each of three coordinates HSI of the position in the 3-dimensional colour space (9) is determined based on data values A ij , D ij , C ij of a corresponding pixel (5) in a respective one of the image data sets A, D, C. For example, the coordinates within the colour space (9) may be indicated by an intensity I, a saturation S and a hue H thereby allowing a very intuitive representation of the complex DPCI measurement data to a human observer.

摘要： The invention relates to a method and an image processing device (10) for the evaluation of image raw-data of a body region generated with an imaging device like a CT scanner (30). From the image raw-data, a first image (I CAD ) is reconstructed with a reconstruction module (12) according to reconstruction parameters (p) set optimally by a computer aided detection and/or diagnosis (CAD) module (13). This module can then evaluate an image (I CAD ) that was reconstructed optimally according to its own requirements, for example with respect to image size and/or resolution, to find features of interest.

摘要： In coherent scatter computed tomography, the scatter angle from object points (31, 32, 33, 34, 35), which are located on a line (36) perpendicular to the central beam (45) in the plane of rotation, varies as a non-linear function of the fan-angle of the detector row (37). According to an exemplary embodiment of the present invention, a single-line energy-resolved detector for CSCT data acquisition is used, which measures scattered photons originating from object points on a circular arc under the same scatter angle. This automatically leads to a Cartesian q- sampling on a parallel-rebinned detector. Advantageously, this may avoid q- interpolation prior to parallel-rebinned filtered back-projection reconstruction.

摘要： The invention relates to a computed tomography method in which a rebinning operation is carried out so as to form parallel fan beams whose rays traverse a plane, containing the axis of rotation, in equidistant puncture points. Reconstruction is performed for rays which extend perpendicularly to said planes. Such a transition from a cone beam geometry to a parallel beam geometry enables very fast reconstruction which can be carried out notably for CT fluoroscopy.

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.
