Abstract
The present application discloses a system and method to calculate the automatic exposure control (AEC) calibrated dosage for tomosynthesis sweeps. For example, reference images may be acquired, and corresponding reference detector count maps may be generated and stored for a plurality of projection angles using the tomosynthesis imaging system. The tomosynthesis imaging system may then acquire a scout image using a scout dosage, identify the densest region within the scout image, and calculated the average detector count values associated with the densest region. The AEC calibrated dosage can be calculated based on a ratio of the average reference detector count values, corresponding to the detector count values of pixels with a corresponding densest region of the reference image, and the calculated average detector count values.
