1. A method for controlling X-ray emissions during three-dimensional X-ray imaging, the method comprising:
obtaining a projection data set acquired in a first three-dimensional X-ray scan of a three-dimensional region of an object;
obtaining a spatially-distributed characteristic of the projection data set, wherein the spatially-distributed characteristic is distributed in a longitudinal direction of the first three-dimensional X-ray scan; and
controlling X-ray emissions of the three-dimensional region during a second three-dimensional X-ray scan based on the spatially-distributed characteristic of the projection data.
