20080226019 | Multiple Scatter Correction - According to an aspect of the present invention, a correction of X-ray intensities measured in an energy-resolved diffraction method may be provided for multiple scattered radiation without any assumptions on the geometry of the object examined. According to an exemplary embodiment of the present invention, the characteristic lines of the anode material in the primary spectrum are evaluated, resulting in a component analysis of the detected spectrum which may allow for a correction for its multiple scatter part. | 09-18-2008 |
20080240342 | Advanced Csct Detector Shapes - The application of CSCT to baggage inspection necessitates a large field of view, resulting in a large gantry that has to sustain large centrifugal forces. Accordingly, various CSCT geometries are described which enable smaller gantry sizes. In particular, a CSCT scanner comprising a detector unit that is not focus-centred is described. | 10-02-2008 |
20080253509 | Acquisition Parameter Optimization For Csct - Whereas the CT image can be acquired in a single revolution, the CSCT image acquisition may require several revolutions. According to an exemplary embodiment of the present invention, a CT/CSCT apparatus may be provided which uses CT data acquired during the first revolution to optimize acquisition parameters for the subsequent revolutions. Furthermore, projection data acquired with a pre-scanner may also be used for determining current modulation or setting an optimum voltage for the subsequent CSCT scan. | 10-16-2008 |

20090245458 | EXTENSION OF THE Q-RANGE IN CSCT - According to an embodiment of the present invention, a reconstruction scheme for a CSCT is provided which is capable of reconstructing data acquired just over a half turn, i.e. 180° plus fan angle. The reconstruction scheme may provide for an extension of the reconstruction towards smaller and larger q-regions as compared with a 360°-reconstruction, if the short scan reconstruction technique is applied to a full scan data set. | 10-01-2009 |
20100034342 | METHOD AND APPARATUS FOR CORRECTING ARTIFACTS IN CIRCULAR CT SCANS - A scanning method and apparatus useful for correcting artifacts which may appear in a primary short circular CT scan are provided. A secondary helical scan performed on a stationary subject, or a secondary circular scan, may be used to correct for artifacts. The secondary scan may be performed with a smaller radiation dosage than the primary circular CT scan. | 02-11-2010 |
