Patent ID: 8873703

Claim:
A method for imaging a subject while correcting scattered radiation scattered from the subject, the method comprising: providing at least a first source of X ray radiation, a detector for the X ray radiation, and a plurality of radiation shields, wherein said plurality of radiation shields is positioned between the first source of x-ray radiation and the detector; irradiating the subject by said first source of X ray radiation and acquiring X ray data from said detector, wherein X rays received by said detector comprise: direct radiation from the first source of x-ray radiation that was attenuated by the subject, and scattered radiation that was scattered by the subject, and wherein shielded parts of a detector area are shaded by said plurality of radiation shields such that said shielded parts are responsive to direct radiation and responsive to scattered radiation, and wherein un-shielded pans of the detector area are responsive to direct radiation and to scattered radiation; correcting the X ray data received by said un-shielded parts of the detector area, wherein correcting scattered radiation is based on scattered radiation data received by said shielded parts of the detector area; and correcting the X ray data received by said shielded pads of said detector area, wherein correcting scatterred radiation is based on direct radiation data received by said unshielded parts of the detector area.
