Abstract

La présente invention a trait à un appareil de localisation par laser pouvant comporter un pointeur laser monté sur une poignée destiné à être disposé mutuellement en parallèle contre la surface d'une tête de détection d'une caméra gamma et un miroir incliné pour orienter le faisceau laser perpendiculairement par rapport à la surface de la tête de détection. La source de rayonnement peut être un bouton contenant du cobalt 57 ou autre matériau radioactif disposé sous le miroir. Lors de la superposition de l'image du matériau radioactif dans l'appareil de localisation par laser sur une image d'une source d'apport radioactif chez le patient sur un moniteur du système, le faisceau laser effectuera automatiquement un pointage vers la source au sein du corps.
