抄録

We previously implemented a conical CT system as X-ray CT system for industrial inspection. But there is the problem, "missing cone" problem, which conical data is missed in fourier space, and vertical accuracy was comparatively low. We intend to improve the vertical accuracy by iterative phase retrieval algorithm. The overall reconstruction algorithm is based on Filtered back projection algorithm and Iterative Phase Retrieval algorithm. We implemented this simulation with the Shepp-Logan phantom, which is often used for CT simulation. Through the study it was revealed that the proposed method can recovery missing data of low frequency.
