A radiological imaging method including: 2 radiation sources with imaging directions orthogonal to each other, performing vertical scanning of a standing patient along a vertical scanning direction, wherein the radiological method includes at least one operating mode in which: a frontal scout view is made so as to identify a specific bone(s) localization within the frontal scout view, both driving current intensity and voltage intensity modulations of the frontal radiation source, depending on patient thickness and on the identified specific bone(s) localization along the vertical scanning direction, are performed simultaneously, preferably synchronously, and automatically, so as to improve a compromise between: lowering the global radiation dose received by a patient during the vertical scanning, and increasing the local image contrasts of the identified specific bone(s) localization at different imaging positions along the vertical scanning direction, for the frontal image.

Disclosed is a method of radiography of an organ of a patient, including: a first vertical scanning of the organ by a first radiation source and a first detector cooperating to make a first two dimensional image of the organ, a second vertical scanning of the organ by a second radiation source and a second detector cooperating to make a second two dimensional image of the organ, the first vertical scanning and the second vertical scanning being performed synchronously, the first and second images viewing the organ of the patient according to different angles of incidence, wherein there is a vertical gap between the first source/detector and the second source/detector, such that the first vertical scanning and the second vertical scanning are performed synchronously but with a time shift in between, so as to reduce cross-scattering between the first and second images.
