Claim 0:
1. A method of radiography of an organ of a patient, the method comprising:
first vertical scanning said organ by a first radiation source and a first detector cooperating to make a first two-dimensional raw image of said organ;
second vertical scanning said organ by a second radiation source and a second detector 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; and
performing computed correction processing on both said first and second raw images, on at least part of data associated with scanned patient height for at least overweight or obese patients, to reduce, between first and second corrected images, cross-scattering existing between said first and second raw images, said computed correction processing on both said first and second raw images comprising:
making a patient-specific model, using at least both of the first and second raw images as patient-specific data, the patient-specific model being a three-dimensional (3D) voxelized reconstruction, obtained from deformation of a generic model to patient-specific radiographic projections corresponding to the first and second raw images,
determining a patient-specific representation of radiation scattering by making said patient specific model by directly simulating scatter signals scattered by the 3D voxelized reconstructions, and
processing said determined patient-specific radiation scattering representation on both said first and second 2D raw images to obtain said first and second corrected images.
