1. A method for monitoring the radiation dose in a body to be imaged during interventional radiography using an X-ray imaging, device comprising an X-ray emitting source, a detector, a processing unit and a display, the method comprising: using the X-ray emitting source to perform successive non-rotational acquisitions from different adjustable exposure angles and exposing the body to be imaged to radiation doses sufficient to acquire initial 2D images during an interventional procedure; computing a 3D model of the body in relation to the initial 2D images using the processing unit; computing a 3D model of a dose repartition in the 3D model of the body using a model of the interactions between matter and radiation using the processing unit; calculating, using the processing unit, a dose map of the distribution of the accumulated radiation dose in a volume of the body for the 3D model for parameters that define the conditions of X-ray exposure; displaying the 3D model of the body oriented according to the position of the emitting source to enable assessment of a given angulation during the interventional procedure; and simultaneously displaying the dose map in the given angulation with the 3D model, wherein the dose map comprises time values of remaining exposure time, in relation to parameters defining the conditions of X-ray exposure and a threshold value of exposure to X-rays that minimizes adverse consequences on the body.
