摘要: A method and system is disclosed that minimizes the effective dose to an object by determining a segmented component map for object, parametrizing tube current/energy level/x-ray filtration/x-ray pulse width as function of time, corresponding absorbed variance map, energy level/tube current profile or curve results in desirable noise throughout image.
