Title (EN) PRECISION REGISTRATION OF X-RAY IMAGES TO CONE-BEAM CT SCAN FOR IMAGE-GUIDED RADIATION TREATMENT
(FR) ALIGNEMENT DE PRECISION D'IMAGES RADIOLOGIQUES SUR UN TOMODENSITOGRAMME A FAISCEAU CONIQUE PERMETTANT D'EFFECTUER UN TRAITEMENT PAR RAYONNEMENT DANS LEQUEL LES IMAGES SERVENT DE GUIDE
Abstract:
(EN) A method for precision registration of X-ray images to cone-beam CT scan for image-guided radiosurgery includes acquiring 2-D pre-treatment X-ray images (802) of a region of interest, acquiring a 2-D X-ray image of the region of interest at approximately a time of treatment (804), registering the 2-D X-ray image with a corresponding 2-D pre-treatment X-ray image to obtain a 2-D registration result at approximately the time of treatment (806), and converting the 2-D registration result into a 3-D tracking result to track the region of interest (807).
(FR) Un procédé d'alignement de précision d'images radiologiques sur un tomodensitogramme à faisceau conique destiné à la radiochirurgie consiste à effectuer l'acquisition d'images radiologiques bidimensionnelles d'une région à traiter, prises avant le traitement, l'acquisition d'une image radiologique bidimensionnelle de la région à traiter approximativement à un moment du traitement, et consiste à aligner une image radiologique bidimensionnelle sur une image radiologique bidimensionnelle avant le traitement correspondante pour obtenir un résultat d'alignement bidimensionnel approximativement au moment du traitement et à convertir le résultat d'alignement bidimensionnel en un résultat de recherche/suivi tridimensionnel pour rechercher/suivre la région à traiter.
