Radiological imaging method comprising: ➢ 2 radiation sources with imaging directions orthogonal to each other, one frontal radiation source and one lateral radiation source, sliding vertically so as to perform vertical scanning of a standing patient along a vertical scanning direction, wherein said radiological method comprises at least one operating mode in which: ➢ a frontal scout view is made by performing a preliminary vertical scanning of a standing patient along said vertical scanning direction by said frontal radiation source, ➢ said frontal scout view is processed (2, 3) to identify a specific bone(s) localization within said frontal scout view, ➢ a driving current intensity of at least said frontal radiation source is modulated along said vertical scanning direction, depending on patient thickness and on said identified specific bone(s) localization along said vertical scanning direction, ➢ a driving voltage intensity of said frontal radiation source is modulated along said vertical scanning direction, depending on patient thickness and on said identified specific bone(s) localization along said vertical scanning direction, ➢ both driving current intensity and voltage intensity modulations of said frontal radiation source are performed simultaneously, preferably synchronously, and automatically, so as to improve a compromise between: ∘ lowering the global radiation dose received by a patient during said vertical scanning, ∘ and increasing the local image contrasts of said identified specific bone(s) localization at different imaging positions along said vertical scanning direction, for the frontal image. ➢ 2 radiation sources with imaging directions orthogonal to each other, one frontal radiation source and one lateral radiation source, sliding vertically so as to perform vertical scanning of a standing patient along a vertical scanning direction, ➢ a frontal scout view is made by performing a preliminary vertical scanning of a standing patient along said vertical scanning direction by said frontal radiation source, ➢ said frontal scout view is processed (2, 3) to identify a specific bone(s) localization within said frontal scout view, ➢ a driving current intensity of at least said frontal radiation source is modulated along said vertical scanning direction, depending on patient thickness and on said identified specific bone(s) localization along said vertical scanning direction, ➢ a driving voltage intensity of said frontal radiation source is modulated along said vertical scanning direction, depending on patient thickness and on said identified specific bone(s) localization along said vertical scanning direction, ➢ both driving current intensity and voltage intensity modulations of said frontal radiation source are performed simultaneously, preferably synchronously, and automatically, so as to improve a compromise between: ∘ lowering the global radiation dose received by a patient during said vertical scanning, ∘ and increasing the local image contrasts of said identified specific bone(s) localization at different imaging positions along said vertical scanning direction, for the frontal image. ∘ lowering the global radiation dose received by a patient during said vertical scanning, ∘ and increasing the local image contrasts of said identified specific bone(s) localization at different imaging positions along said vertical scanning direction, for the frontal image.
