Abstract:BackgroundWith advanced x‐ray source and detector technologies being continuously developed, non‐traditional CT geometries have been widely explored. Generalized‐Equiangular Geometry CT (GEGCT) architecture, in which an x‐ray source might be positioned radially far away from the focus of arced detector array that is equiangularly spaced, is of importance in many novel CT systems and designs.PurposeGEGCT, unfortunately, has no theoretically exact and shift‐invariant analytical image reconstruction algorithm in … Show more
