A computer-simulated radioscopy method for use in surgery, and particularly in microsurgery, wherein an exhaustive volumetric acquisition of digital images of the operating region is performed; a set of static sensors (16) is placed on the patient to determine a referential of at least three-dimensional co-ordinates; the acquired digital images and the referential are correlated; all of the operative features of the microinstruments (24) to be used by the surgeon during the operation are digitally input; a dynamic topological sensor (18) is lockably attached to the microinstrument used (24) in a predetermined position; the position of the dynamic sensor in relation to the referential is constantly monitored and the exact position of the distal end of the microinstrument (24) is calculated; and the exact position of at least the distal end of the microinstrument (24) on the corresponding digital image is displayed in real time on a screen (4) during the operation. |
