An New Filtered Back-projection Algorithm.

Abstract: The Filtered Back-projection Algorithm is a relatively perfect algorithm in turntable imaging, it is widely used in CT and signal processing. It is found though analyzing that the time frequency coupling is neglected and the imaging quality descends. A new Filtered Back - projection Algorithm is proposed. The new method is tested using of practice measure data and numerical simulations, which shows that the new algorithm is effective. [Copyright &y& Elsevier]
