PROCEDE DE DETECTION D'UN CHAMP ELECTROMAGNATIQUE DANS UN SYSTEME D'IMAGERIE ET DISPOSITIF PERMETTANT D'AMELIORER LA QUALITE D'IMAGE DANS UN SYSTEME D'IMAGERIE.

摘要

The method involves emitting an electromagnetic field (160) by an electromagnetic emitter (150) of a surgical navigation system. The electromagnetic field is measured using a detector (120) e.g. flat panel amorphous silicon X-ray, of a digital imaging system (100), where the detector reads an image of an object (140) and a field image. The field image from the detector is read based on the electromagnetic field. The field image read from the detector is processed by an image processing unit (130). A position of an element e.g. surgical tool, is determined based on the electromagnetic field.
