The invention relates to a computerized imaging method for three-dimensional reconstruction from two-dimensional radiological images. For this purpose, a set of surface markers (26, 26 ') detectable by a surface sensor (4) for acquiring three-dimensional or 3D surface images of the surface of the subject is placed on the subject's surface. surface markings being also radio-opaque; each acquired radiological image (3, 3 ') is associated with a corresponding surface image acquired substantially at the same time; an iterative process including an incidence calculation phase (10) and an iterative process deformation calculation phase (11) is performed to determine (15) the relative positions of the radiological images and the surface images. as well as performing a positioning (16) in the three dimensions of the radiological images by supposing an absence of deformation of the subject, and intended to determine (19) and correct (21) on the radiological images the deformations of the subject for the relative positions determined in the incidence calculation phase, the stop criterion of the iteration being based on the difference (23) between the 3D coordinates of the marks between two successive iterations.
