Abstract
(EN) Provided is a skull slicing method. By means of establishing a six-view datum plane of a skull three-dimensional model, limiting the range of horizontal plane slices by means of an upper-view datum plane and a lower-view datum plane, limiting the range of sagittal plane slices by means of a left-view datum plane and a right-view datum plane, and limiting the range of coronal plane slices by means of a front-view datum plane and a rear-view datum plane, the generation of a large number of empty slices is effectively prevented, such that the analysis rate of slice data is accelerated.
(FR) L'invention concerne un procédé de découpe de crâne. Grâce à l'établissement d'un plan de référence à six vues d'un modèle tridimensionnel de crâne, à la limitation de la plage de coupes de plan horizontal au moyen d'un plan de référence de vue supérieure et d'un plan de référence de vue inférieure, à la limitation de la plage de coupe de plan sagittal au moyen d'un plan de référence de vue de gauche et d'un plan de référence de vue de droite et à la limitation de la plage de coupes de plan coronal au moyen d'un plan de référence de vue de face et d'un plan de référence de vue arrière, la génération d'un grand nombre de coupes vides est empêchée efficacement, de sorte que la vitesse d'analyse de données de coupe est accélérée.
(ZH) 本发明提供了一种颅骨的切片方法,通过建立颅骨三维模型的六视基准面,并以上视基准面和下视基准面限定水平面切片的范围,以左视基准面和右视基准面限定矢状面切片的范围,以前视基准面和后视基准面限定冠状面切片的范围,有效避免大量空切片的产生,从而加快对切片数据的分析速率。
