Abstract

Rotate-rotate fan beam configuration commonly used in the third generation x-ray computed tomography scanners is susceptible to ring artifacts resulting from non-uniform detector response. A method which incorporates the relative variation of the angular velocities of the x-ray tube and the detector array is proposed. Simulation results utilizing the new technique are presented and compared with the third and fourth generation scanners.
