Selection of optimal viewing angle to optimize anatomy visibility and patient skin dose

摘要

The invention relates to a method for monitoring the radiation dose in a body to be imaged using an X-ray imaging device comprising a X-ray emitting source, a detector, a processing unit and a display, provided with: –  a 3D model capable of identifying different elements of the body, –  a model of the interactions between matter and radiation, which is to be applied to said 3D model, –  parameters defining the conditions of X-rays expositions, and comprising a calculation step which is made of a dose map of the distribution of the accumulated radiation dose in said 3D model for said parameters, characterized in that said 3D model of the body oriented according to the position of the emitting source is displayed together with the dose map so that the user can perform a trade-off between the exposition of the body to X-rays and the interest of the angulations for anatomy assessment.
