Abstract

In a previous study, an exact and computationally efficient cone beam reconstruction algorithm for the circular-and-line orbit was proposed and its excellent numerical performance was demonstrated.In this paper, we define the scan field-of- view (FOV) of the system as a cylinder ended with a cone at each end, whose axes coincide with the axis of rotation. We demonstrate that an exact regional reconstruction of the longitudinally-unbounded object can be achieved with this system within the scan FOV. This and the previous studies combined defines a simple and practical cone beam tomographic system and an exact and computational efficient reconstruction for general imaging applications.
