Methods and systems for aluminum filtration detection

Abstract

Various methods and systems are provided for X-ray imaging systems. In one example, a method for measuring an equivalent aluminum filtration of a tabletop comprises acquiring a single X-ray image of a tabletop and an aluminum filtration scale using a detector; identifying a brightness of the tabletop and a brightness of the aluminum filtration scale in the single X-ray image; computing an aluminum equivalence of the tabletop, converting the brightness of the aluminum filtration scale to an air KERMA of the aluminum filtration scale and converting the aluminum equivalence of the tabletop to an air KERMA of the tabletop; and comparing the air KERMA of the tabletop to the air KERMA of the aluminum filtration scale to identify an air equivalent aluminum filtration of the tabletop.
