Abstract
A device, as disclosed, may be suitable for use with a tomographic imager comprising an X-ray source and a plane detector that are movable in rotation. The device (e.g., radiopaque device) includes a registration phantom that includes several radiopaque markers and that is placeable along a part of the spine of a patient at a predetermined distance from a volume of interest to be imaged. Several radiopaque screens, integral with the registration phantom, include a lower face, an internal face oriented toward the registration phantom, and an external face oriented toward the X-ray source (410), respectively towards the detector. The radiopaque device is configured so that, when it is placed on the back of a patient, at least part of the X-rays that pass from the X-ray source to the plane detector through the registration phantom see their intensity attenuated by passing through the radiopaque screens.
