Title (EN) COMPOSITE RADIOGRAPHIC IMAGE THAT CORRECTS EFFECTS OF PARALLAX DISTORTION
(FR) IMAGE RADIOGRAPHIQUE COMPOSITE CORRIGEANT LES EFFETS D'UNE DISTORSION DE PARALLAXE
Abstract:
(EN) The present disclosure is directed toward systems and methods for generating a composite radiographic image that corrects effects of parallax distortion. A sequence of radiographic images— including a series of discrete exposures or image frames from a fluoroscopic procedure— may be acquired using a C-arm apparatus. An exemplary method may include receiving a plurality of radiographic image frames pertaining to a patient, identifying a region of interest on the image frames, cropping the region of interest from a plurality of image frames, selecting a plurality of sequential portions of cropped image frames, and stitching together the selected portions to form a composite image that corrects effects of parallax distortion.
(FR) La présente invention concerne des systèmes et des procédés permettant de générer une image radiographique composite qui corrige les effets d'une distorsion de parallaxe. Une séquence d'images radiographiques, comprenant une série d'expositions ou de trames d'image distinctes issue d'une procédure radioscopique, peut être acquise à l'aide d'un appareil à arceau. Un procédé donné à titre d'exemple peut consister à recevoir une pluralité de trames d'image radiographique concernant un patient, à identifier une région d'intérêt sur les trames d'image, à rogner la région d'intérêt à partir d'une pluralité de trames d'image, à sélectionner une pluralité de parties séquentielles de trames d'image rognées, et à assembler les parties sélectionnées pour former une image composite qui corrige les effets de la distorsion de parallaxe.
