title = "An improved exact FBP algorithm for image reconstruction in cone-beam helical CT",
abstract = "Recently, Katsevich proposed an exact FBP algorithm and its improved version for image reconstruction in helical cone-beam CT. In this paper, we present a new FBP image reconstruction algorithm by modifying Katsevich's original algorithm.This new algorithm is easier to implement and more efficient than the improved version of Katsevich's algorithm. Numerical simulations are performed to validate the proposed exact FBP algorithm. Results in these studies confirm the observation that the proposed algorithm can improve the image resolution over Katsevich's original algorithm with noiseless and noise projection data.",
