Abstract
A method for image reconstruction and reducing patient dose, and an imaging system for accomplishing these methods, includes selecting a primary phase of a cardiac cycle and calculating compromised phase regions based on a selected compromised phase value. If the image position is located within the primary phase, then an image is generated at the primary phase. If the image position is not located within the primary phase, but is located within a compromised phase region, then an image is generated at the compromised phase region.
