Abstract

The invention relates to a recalibration device () used during the acquisition of images of an anatomical area of a patient during robot-assisted surgery, including a body () made of radxoliacent material, which comprises fiducial markers () made of radiopaque material, said body () having a bearing surface () intended to be manually placed on a surface of said anatomical area of the patient. According to the invention, said fiducial markers () are arranged in a specific geometrical pattern enabling a certain detection of the positioning and orientation of the recalibration device () in a three-dimensional digital model built from the images derived from the acquisition of the anatomical area.
