    • An X-CT scan system includes a base, an object rotary support, an X-ray generation device and a data acquisition system, wherein one side of the detector is leveled to or beyond the prolong line of the connecting line between the X-ray source of the X-ray generation device and the center of the object rotary support, the length of the beyond portion is less than the radius of the imaging field. The advantage of the invention is in that the invention can reconstruct the entire image of the object by means of X-ray projection data which only covers half of the area of the object. Compared with the traditional CT scan system, half of the detector size can be saved at most. The X-CT scan system is simplified and the projection data amount for scan and computation amount for image reconstruction are also reduced with the reconstructed image quality guaranteed.
    • X-CT扫描系统包括基座,对象旋转支架,X射线产生装置和数据采集系统,其中检测器的一侧被平整到或超过X射线之间的连接线的延长线 X射线产生装置的源和对象旋转支架的中心,超出部分的长度小于成像场的半径。 本发明的优点在于,本发明可以通过仅覆盖对象区域的一半的X射线投影数据来重建物体的整个图像。 与传统CT扫描系统相比,检测器尺寸的一半最多可以节省。 X-CT扫描系统被简化,并且用于图像重建的扫描和计算量的投影数据量也被减少,重建图像质量得到保证。

    • A method, system and program storage device are provided for extending an inverted index, which comprises first and second inverted index subfiles to increase the speed of establishing and updating inverted index files. The method includes performing ordered keyword indexing operations of generating an inverted index from data sources, in which a frequency of occurrence of keywords in each of the data sources is calculated, and writing each keyword, the data sources, and the frequency of occurrence of each keyword in the corresponding data sources to the inverted index. If a number of data sources involved in the indexing operations reaches a first threshold, then writing contents of the inverted index as a smallest grid into the first inverted index subfile. If a number of smallest grids in the first inverted index subfile reaches a second threshold, then merging the smallest grids into a merged grid and writing the merged grid into the second inverted index subfile. If the number of merged grids in the second inverted index subfile reaches a third threshold, then further merging the merged grids into a larger merged grid, and writing the larger merged grid back into the first inverted index subfile.
    • 提供了一种用于扩展反向索引的方法,系统和程序存储装置,其包括第一和第二反向索引子文件,以增加建立和更新反向索引文件的速度。 该方法包括执行从数据源生成反向索引的有序关键字索引操作,其中计算每个数据源中的关键字的发生频率,并且写入每个关键字,数据源和每个数据源的发生频率 关键字在相应的数据源中反转索引。 如果涉及索引操作的数据源数目达到第一阈值,则将反向索引的内容作为最小格网写入第一反向索引子文件中。 如果第一反向索引子文件中的最小格数达到第二阈值,则将最小网格合并到合并的网格中,并将合并的网格写入第二个反向索引子文件。 如果第二反向索引子文件中的合并网格数达到第三阈值,则将合并的网格进一步合并到较大的合并网格中,并将较大的合并网格写回第一个反向索引子文件。

    • Described are various embodiments which enable organizations to track and use knowledge and expertise of their associated individuals. An organization can use exemplary embodiments to automatically summarize the expertise of each individual from documents available from internal or external web sites. For example, a web crawler crawls a computer network to identify documents that name an individual. Summaries of the documents are generated based on articles in an encyclopedia, and a profile is built of the individual using the summaries. These summaries are used for automatically searching and automatically discovering individuals having particular knowledge or expertise on certain topics and subjects.
