摘要： One or more techniques and/or systems are described herein for cleaning a portion of a radiographic examination apparatus whereon debris may accumulate. Typically, the portion being cleaned is within a scanning field of the radiographic examination device (e.g., within a portion of the radiographic examination device through which radiation traverses). Activation of a cleaning mechanism, or a portion thereof, may be timed to miss radiation emitted during a scan, and thus not interfere with a scan. Also, the cleaning mechanism, or a portion thereof, may be located so as to not attenuate radiation. If radiation is attenuated by the cleaning mechanism corrective techniques can be implemented to account for such attenuation.

摘要： One or more systems and/or techniques are disclosed herein for determining the orientation of a focal spot of a radiation source based upon shadows that are imposed on channels of a detector array from an anti-scatter grid. The anti-scatter grid is comprised of one or more anti-scatter plates that are focused on a point other than an intended focal spot of the radiation source. Such anti-scatters plates cast shadows on the detector array (even when the focal spot is located at the intended focal spot). By measuring changes in the signals generated by channels of the detector array that detect the shadows, it may be determined how the orientation of the focal spot has changed throughout an examination or between a calibration scan and an examination scan, for example.

摘要： Among other things, one or more systems and/or techniques for integrating electrical charge yielded from an indirect conversion detector array of a pulsating radiation system are provided. The integration begins during a resting period between a first and second pulse and ends before the second pulse is emitted. Electrical charge that is measured during a resting period is integrated, while electrical charge measured during a pulse is not integrated. In this way, parasitic contributions caused by the direct interaction of radiation photons with a photodiode are reduced and a quantum efficiency of the indirect conversion detector array is increased, for example. Moreover, the period of integration can be adjusted such that a voltage gain related to the indirect conversion detector array can be varied to a predetermined level.
摘要翻译：提供了一种或多种用于积分从脉动辐射系统的间接转换检测器阵列产生的电荷的系统和/或技术。积分在第一和第二脉冲之间的静止期间开始，并且在第二脉冲发射之前结束。在静止期间测量的电荷被积分，而在脉冲期间测量的电荷未被积分。以这种方式，减少了由辐射光子与光电二极管的直接相互作用引起的寄生贡献，并且例如间接转换检测器阵列的量子效率增加。此外，可以调节积分周期，使得与间接转换检测器阵列相关的电压增益可以变化到预定水平。

摘要： A CT detector cell is constructed to have diagonally oriented perimeter walls. With such a construction, the resulting CT detector comprised of such detector cells has improved spatial coverage (spatial density). The number of detector channels is also not increased despite the increase in spatial coverage. Moreover, the detector cells can be constructed without much variance from conventional fabrication techniques.

摘要： A method for reducing artifacts in computed tomographic (CT) images is provided that is particularly useful for CT applications requiring higher gantry rotation rates. The method includes selecting a set of thresholds for projection view data; utilizing a smoothing kernel in accordance with the selected set of thresholds to produce a set of smoothed projections from a set of original projections obtained from a scan of an object, wherein an amount of smoothing applied varies depending upon a relationship of the original projections to the thresholds; producing a set of final projections utilizing the set of original projections and the set of smoothed projections; and reconstructing images of the object utilizing the final projections.
