    • A method and apparatus for performing computed tomography in medical imaging through reconstruction of a data set containing projections obtained during relative motions a container or body of interest with respect to an x-ray source and/or x-ray detector panel. Strobing of the data is implemented through one or more methods to include pulsing of the x-ray source, intermittent blanking of the x-ray detector panel, or intermittent processing of data collected from the detector panel to simulate blanking. The invention is utilized to significantly improve contrast by taking advantage of the pulsed nature of the source to implement three-dimensional reconstruction.
    • 一种用于在医学成像中执行计算机断层摄影的方法和装置,通过重建包含在相对运动期间获得的相对于X射线源和/或X射线检测器面板的感兴趣的容器或体内的突起的数据集。 通过一种或多种方法来实现数据的扫描以包括x射线源的脉冲,x射线检测器面板的间歇性消隐,或间歇地处理从检测器面板收集的数据以模拟消隐。 本发明用于通过利用源的脉冲特性来实现三维重建来显着改善对比度。
