Title (EN) IMAGE REGISTRATION OF TREATMENT PLANNING IMAGE, INTRAFRACTION 3D IMAGE, AND INTRAFRACTION 2D X-RAY IMAGE
(FR) ENREGISTREMENT D'IMAGE DE PLANIFICATION DE TRAITEMENT, IMAGE 3D INTRAFRACTION, ET IMAGE RADIOGRAPHIQUE 2D INTRAFRACTION
Abstract:
(EN) A method of the present disclosure includes performing, by a processing device, a first image registration between a reference image of a patient and a motion image of the patient to perform alignment between the reference image and the motion image, wherein the reference image and the motion image include a target position of the patient. The method further includes performing, by the processing device, a second image registration between the reference image and a motion x-ray image of the patient, via a first digitally reconstructed radiograph (DRR) for the reference image of the patient. The method further includes tracking at least a translational change in the target position based on the first registration and the second registration.
(FR) La présente invention concerne un procédé consistant à réaliser, par un dispositif de traitement, un premier enregistrement d'image entre une image de référence d'un patient et une image de mouvement du patient pour effectuer un alignement entre l'image de référence et l'image de mouvement, l'image de référence et l'image de mouvement comprenant une position cible du patient. Le procédé consiste en outre à réaliser, par le dispositif de traitement, un second enregistrement d'image entre l'image de référence et une image radiographique de mouvement du patient, par l'intermédiaire d'une première radiographie reconstruite numériquement (DRR) pour l'image de référence du patient. Le procédé consiste en outre à suivre au moins un changement de translation dans la position cible sur la base du premier enregistrement et du second enregistrement.
