Abstract :
In this work we suggest ways to incorporate redundant data into reconstruction for a range of helical pitches from 1-PI to 3-PI. For evaluation we use simulated data and real 256-slice anthropomorphic phantom data. With large cone angle reconstruction is very sensitive to the exactness of the algorithm.
