Abstract: The invention relates to a method for indicating an incision trajectory, by an intraoperative imaging system (1) comprising a laser source (13), comprising the following steps:—acquiring two X-ray images of a region of interest at different acquisition angles;—designating, by a user, an element (33) on a displayed acquired image (32);—computing, by a control unit, a target point (TP), based on a determined anatomical information of the patient (100) and on the designated element;—indicating an incision trajectory to be followed to reach the target point (TP), by generating a laser beam (14) adapted to; o mark the incision point (IP) on the patient's skin (110); and o indicate the incision direction (ID) by an interaction between the laser beam (14) and an incision tool (20).

Abstract: The invention relates to an X-ray imaging system comprising a mobile base (10), a motorized arm (20), and a C-arm (30) adapted to be mounted on the mobile base (10) by means of the motorized arm (20), wherein the C-arm (30) comprises an X-ray source (31) and an X-ray detector (32), wherein the motorized arm (20) presents at least three rotation axes (Z1, Z2, Z3) directed along a substantially common vertical direction (Z).
