Performances of ROSEM,CBP and ART are analyzed on both Sheep-Logan digital phantom and the ~(60)Co Container inspection system. ROSEM exceeds ART in both speed and image quality,but exhibits a slower speed than CBP.

• 针对ROSEM、代数迭代算法(ART)和卷积反投影算法(CBP),分别做了模拟实验和实际汽车CT检测以及集装箱CT检测实验,并分析比较了它们在60Co集装箱CT检测中的应用。
