三维CT在锥角增大时对重建图像质量的影响

The Effect of Cone Angle Being Increased on the 3D CT Reconstruction Capability

通过分析圆柱状物体在不同锥角时对重建图像质量的影响 ,从而得出传统三维 CT适宜于小锥角(大约 6°)

The effects on the reconstruction capability for cylindrical objects at different cone angles are analysed. We draw a conclusion that the conventional 3D CT reconstruction are adapted to the reconstruction at small cone angle(less than 6 degree).
