Title
(EN) SYSTEM AND METHOD FOR SEGMENTING TEETH IN CT IMAGE
(FR) SYSTÈME ET PROCÉDÉ DE SEGMENTATION DE DENTS DANS UNE IMAGE DE TOMODENSITOMÉTRIE
(KO) CT 영상에서의 치아 분할 시스템 및 방법
Abstract
(EN) The present disclosure relates overall to a system and a method for segmenting teeth, and more specifically relates to a system and a method for segmenting teeth which segment teeth from a dental CT image. The system and method for segmenting teeth, according to one embodiment of the present invention, can segment teeth by extracting not only the crown portion of a tooth but also extracting as far as the dental root area.
(FR) La présente divulgation concerne globalement un système et un procédé de segmentation de dents, et plus particulièrement un système et un procédé de segmentation de dents qui segmentent des dents à partir d'une image de tomodensitométrie dentaire. Le système et le procédé de segmentation de dents, selon un mode de réalisation de la présente invention, peuvent segmenter des dents en extrayant non seulement la partie couronne d'une dent mais également en extrayant jusqu'à la zone de racine dentaire.
(KO) 본 개시(Disclosure)는 전체적으로 치아 분할 시스템 및 방법에 관한 것으로, 더욱 상세하게는 치과용 CT 영상으로부터 치아를 분할하는 치아 분할 시스템 및 방법에 관한 것이다. 본 발명의 하나의 양상에 따르는 치아 분할 시스템 및 방법은 치아의 크라운뿐만 아니라 치근 영역까지 추출하여 치아를 분할할 수 있다.
