新的滤波-逆投影成像算法
New filtered back-projection algorithm
摘要
Abstract
The filtered back-projection algorithm is relatively perfect algorithm in turntable imaging,it is widely used in CT and signal processing.The time frequency coupling of the algorithm is neglected,so making imaging quality dcscend.A new filtered back-projection algorithm is proposed.The new method is tested by using practice measure data and simulating data,the experimentation results show that the new algorithm is effective.关键词
