Fig. 2From: Robotic assistance for percutaneous needle insertion in the kidney: preclinical proof on a swine animal modelTechnique of evaluation of accuracy based on a CT obtained after needle insertion. Reconstruction along the needle axis in the plane of the centre of the targeted fiducial is used for measurement of depth deviation, lateral deviation and three-dimensional distance (a).
