Abstract
A method for gating in tomographic imaging system includes steps of: (a) performing a tomographic imaging on an object for acquiring a plurality of projection images at different projection angles, wherein a target of the object moves periodically; (b) obtaining a projected position of the target on each of the projection images, wherein the projected position is a center of a target zone on each of the projection images; (c) calculating a parameter value of pixel values in the target zone on each of the projection images, and obtaining a curve of a moving cycle of the target according to the parameter values of the projection images; and (d) selecting the projection images under the same state in the moving cycle for image reconstruction according to the curve of the moving cycle of the target.
