| Abstract: | Firstly the accurate filter back projection reconstruction algorithm is derived when the moving distance between the rotation centre and the central line of fan beam is the function of the rotation angle. Then the reconstruction algorithm is derived when this function is the linear one. Finally the correctness of these two algorithms are proved by the computer simulation. |
