Patent ID: 7657001

Claim:
A method for reducing differential ghosting in an X-ray image acquired in respect of a subject using an X-ray system comprising an X-ray source for irradiating said subject and an X-ray detector for receiving X-radiation that has passed through said subject and generating an electric signal representative of the intensity distribution thereof, said X-ray detector comprising a scintillator for receiving X-radiation incident thereon and converting said X-radiation into optical radiation, the method comprising acts of: prior to acquiring the X-ray image, acquiring a deghost scan when no subject is present between said X-ray source and the X-ray detector by causing said X-ray source to generate an X-radiation beam at a higher X-radiation dose than when the x-ray image is acquired, and causing said detector to receive said X-radiation and generate an electric signal representative of homogeneous ghosting caused in said detector by said X-radiation incident thereon.
