Method of radiography of an organ of a patient, comprising: - a first vertical scanning of said organ by a first radiation source (1, 201) and a first detector (3, 203) cooperating to make a first two dimensional raw image of said organ, - a second vertical scanning of said organ by a second radiation source (2, 202) and a second detector (4, 204) cooperating to make a second two dimensional raw image of said organ, - said first vertical scanning and said second vertical scanning being performed synchronously, - said first and second raw images viewing said organ of said patient according to different angles of incidence, wherein a computed correction is processed on both said first and second raw images, on at least part of patient scanned height, for at least overweight or obese patients, so as to reduce, between first and second corrected images, cross-scattering existing between said first and second raw images, and wherein said computed correction processing on both said first and second raw images comprises: ➢ a step (32, 33, 34, 53, 121) of making a patient specific modeling, using as patient specific data therefore at least both first and second raw images, preferably mainly both first and second raw images, more preferably only both first and second raw images, ➢ a step (34, 35, 54, 122, 123) of determining a patient specific representation of radiation scattering by said patient specific modeling, ➢ a step (36, 55, 124) of processing said patient specific radiation scattering representation on both said first and second raw images so as to get said first and second corrected images, and wherein there is a vertical gap between on the one hand said first source and detector and on the other hand said second source and detector, such that said first vertical scanning and said second vertical scanning are performed synchronously but with a time shift in between, so as to further reduce cross-scattering between said first and second raw images. - a first vertical scanning of said organ by a first radiation source (1, 201) and a first detector (3, 203) cooperating to make a first two dimensional raw image of said organ, - a second vertical scanning of said organ by a second radiation source (2, 202) and a second detector (4, 204) cooperating to make a second two dimensional raw image of said organ, - said first vertical scanning and said second vertical scanning being performed synchronously, - said first and second raw images viewing said organ of said patient according to different angles of incidence, wherein a computed correction is processed on both said first and second raw images, on at least part of patient scanned height, for at least overweight or obese patients, so as to reduce, between first and second corrected images, cross-scattering existing between said first and second raw images, and wherein said computed correction processing on both said first and second raw images comprises: ➢ a step (32, 33, 34, 53, 121) of making a patient specific modeling, using as patient specific data therefore at least both first and second raw images, preferably mainly both first and second raw images, more preferably only both first and second raw images, ➢ a step (34, 35, 54, 122, 123) of determining a patient specific representation of radiation scattering by said patient specific modeling, ➢ a step (36, 55, 124) of processing said patient specific radiation scattering representation on both said first and second raw images so as to get said first and second corrected images, ➢ a step (32, 33, 34, 53, 121) of making a patient specific modeling, using as patient specific data therefore at least both first and second raw images, preferably mainly both first and second raw images, more preferably only both first and second raw images, ➢ a step (34, 35, 54, 122, 123) of determining a patient specific representation of radiation scattering by said patient specific modeling, ➢ a step (36, 55, 124) of processing said patient specific radiation scattering representation on both said first and second raw images so as to get said first and second corrected images, and wherein there is a vertical gap between on the one hand said first source and detector and on the other hand said second source and detector, such that said first vertical scanning and said second vertical scanning are performed synchronously but with a time shift in between, so as to further reduce cross-scattering between said first and second raw images.
