| 摘 要： | 在常规的CT扫描方式下，对于一些形如扁平体的试件，通常受旋转空间或探测器动态范围的限制而得不到完整的投影，也就不能完成CT重构。但在非常规的CT扫描方式下能用低能的X射线源完成这些形如扁平体试件的CT重构，节省了能量。

| Abstract: | Under the conventional CT scanning mode, some specimens with the flat-type can't fulfill the CT reconfiguration because they are failing to get the complete projection being restricted by the rotated space or detector's dynamic scope. However under the unconventional CT scanning mode, using the low-energy X-ray source, which can save the energy, can fulfill the CT reconfiguration of the specimens with the flat-type. |
