An imaging system and method configured to construct an image of an internal structure of an object. The imaging system including: a radiation source configured to generate both a narrow beam and a wide beam of radiation a detector configured to detect the radiation and at least one processing circuit configured to: determine a scatter-to-primary ratio (SPR) of the wide beam based on the narrow beam determine a primary component of the wide beam based on the SPR to thereby separate the primary component from a scattered component of the wide beam and construct the image using the primary component.
