非常规CT三维重建中滤波函数的选取

Option of Filter Function of 3D Reconstruction in Abnormal CT

文中根据非常规CT重建的特点,选择适合的卷积函数,对重建出的二维切片沿锥面滤波。对比不同卷积函数的重建结果验证了选择该函数的正确性.

Flat piece is widely used in industrial production.CT reconstruction toward flat piece has great practical importance.According to the characteristic of the abnormal CT reconstruction,selecting suitable filter function, filtering the reconstructed 2D section image along the pyramidal face ,the validity of this function is verified by contrasting different reconstructed results by using different filter functions.
