The cone-beam approach for image reconstruction attracts an increasing attention in various applications, especially medical imaging. Previously, the traditional practical cone-beam reconstruction method, the Feldkamp algorithm, was generalized into the case of spiral/helical scanning loci with equispatial cone-beam projection data. In this paper, we formulated the generalized Feldkamp algorithm in the case of equiangular cone-beam projection data. Because medical multi-slice/cone-beam computed tomography (CT) scanners typically use equiangular projection data, our new formula may be useful in the area of medical X-ray imaging.
