摘要: 滤波-逆投影是一种公认的比较理想的转台成像方法,广泛应用于很多领域。但该算法忽略了时频耦合问题,使其成像效果受到了一定的影响。为此,提出了一种新型的滤波-逆投影算法。经过实验分析对比,证明了新算法的有效性。

关键词: 时频耦合, 滤波-逆投影, 成像

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 descend.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.

Key words: time frequency coupling, filtered back-projection, imaging
