1. A radiopaque device for a cone-beam reconstruction technique X-ray imaging system, the X-ray imaging system comprising a cone emitting X-ray source and a plane detector, the X-ray source and the plane detector being integral with one another and movable in rotation in a substantially vertical imaging plane around an axis of rotation and passing through a volume of interest of a patient to be imaged, the radiopaque device comprising:
a registration phantom comprising a set of at least three radiopaque markers arranged in a known three-dimensional configuration and placeable at a predetermined distance from the volume of interest to be imaged; and
a set of at least one radiopaque screen, integral with the registration phantom, the at least one radiopaque screen comprising:
a lower face;
an internal face oriented toward the registration phantom; and
an external face opposed to the internal face,
the radiopaque device being configured so that, when the radiopaque device is placed on the patient, at least part of X-rays from an emitting cone and that pass from the X-ray source to the plane detector through the registration phantom see their intensity attenuated by passing through the set of at least one radiopaque screen.
