最后，通过工程实例分析表明，在大跨度屋盖结构中，金属蜂窝板-杆空间结构体系比常规的四角锥网架结构具有用钢量低，结构整体自重轻等优点；在轻钢结构厂房中，采用金属蜂窝纯板片箱梁体系比一般H型钢结构用钢量更低，自重更轻，具有广泛的应用前景。

Image reconstruction from the projections of fan-beam: The CT equipment is broadly adopted on the world that its detectors are arranged on the concentric circle at same angle interval. This equipment rebates the complex machinery movements like parallel-beam geometry, makes the sampling time shorter, that is rebating the whole CT testing time.

扇形束图象重建：将探测器等角间隔排列于同心圆周上采集射线投影数据，然后进行图象重建的CT装置是目前世界上广为使用的，它减少了平行射束采样方式的繁杂的机械运动，可有效地缩短数据采集时间，也就是减少了CT检测的总的花费时间。
