| 摘 要： | 在实际的CT重建中,由于受散射、射束硬化等低频干扰因素的影响,使得重建图像产生"杯状”伪像以及图像模糊降质.针对在ICT工程实践中投影数据存在诸如此类的低频污染问题,本文提出了一新型实用滤波函数取代传统的滤波函数,得到了较为满意的重建效果.

| Abstract: | In practical CT, the reconstructed image is degraded by the affects of beam hardening. scattering and other facts .In order to dispose of the affects of such low-frequency pollution, the author proposes a new practical filter function to displace conventional filter function, and some satisfying results are got. |
