摘要

A method is provided for monitoring the radiation dose in a body to be imaged using an X-ray imaging device comprising an X-ray emitting source, a detector, a processing unit and a display. The method comprises exposing the body to be imaged to radiation doses to acquire initial 2D images; computing a 3D model of the body in relation to the initial 2D images using the processing unit; applying a model of the interactions between matter and radiation to the 3D model of the body using the processing unit; calculating, using the processing unit, a dose map of the distribution of the accumulated radiation dose in the 3D model for parameters that define the conditions of X-ray exposure; and displaying the 3D model of the body oriented according to the position of the emitting source with the dose map.
