    Abstract: The invention relates to a method for determining a safety criterion during an autonomous manipulation of a surgical tool (13) by a robotic system (1) to treat an anatomical structure (B) according to a planned trajectory (T3D) in a 3D image (I3D), said 3D image being registered with a patient tracker (30), and the robotic system (1) being servo-controlled on the movements of the patient tracker (30), the method comprising: a. acquiring at least one 2D X-ray image (I2D) containing the anatomical structure and the surgical tool by an X-ray imaging system (2), and for each at least one 2D X-ray acquisition: i. synchronously localizing the surgical tool and the patient tracker to determine the position of the surgical tool relative to said 3D image, ii. registering the 2D X-ray image (I2D) with the 3D image (I3D) in a region of interest around the anatomical structure, iii. generating a projection onto the 2D X-ray image (I2D) of a model of the surgical tool in its position relative to the 3D image computed in step (i) ('projected localized position'), iv. determining a real position of the surgical tool on the 2D X-ray image (I2D) ('real position'), b. determining a safety criterion from a similarity information between each real position and each projected localized position of the surgical tool on the at least one 2D X-ray image.

    Abstract: The invention relates to a method for optimizing a trajectory of a motorized C-arm for an acquisition of a 3D image of a region of interest (ROI) of a body (P) lying on an operating table (T), said C-arm comprising an X-ray source (S) and an X-ray image detector (D), said trajectory comprising at least two different angular positions of acquisition around a rotation axis of the C-arm, said method comprising the following steps: determining a center (C) of the region of interest (ROI) for each angular position of the C-arm of said trajectory, computing a translation (TA) of the C-arm along a central axis extending between the X-ray source (S) and a center of the X-ray image detector (D) and passing by said center (C) of the region of interest to reduce a distance between the X-ray image detector (D) and the center (C) of the region of interest whilst avoiding collisions between the X-ray source and detector and the operating table (T) and/or the body (P).
