【摘要】运用虚拟现实建模语言(VRM L)进行医学脏器三维重建,探讨JavaScript语言在重建后模型动态切割中的应用。基于患者实例,在对D ICOM 3.0标准医学二维图像后处理基础上,利用VRM L建模进行脏器三维重建并利用VRM L的Script节点、传感器节点,实现三维医学模型的动态切割。通过VRM L建模得到较高质量的脏器立体图像并提供较好的人机实时交互环境,结合JavaScript能实现重建脏器的动态切割、移动、旋转等功能。利用VRM L建模进行医学脏器三维重建并结合JavaScript对三维模型进行动态切割,在成像质量和实时交互性等方面具有一定的优越性,有较大的临床实际应用价值。更多还原

【Abstract】 This research studies the process of dynamic concision and 3D reconstruction from medical body data using VRML and JavaScript language,focuses on how to realize the dynamic concision of 3D medical model built with VRML.The 2D medical digital images firstly are modified and manipulated by 2D image software.Then,based on these images,3D mould is built with VRML and JavaScript language.After programming in JavaScript to control 3D model,the function of dynamic concision realized by Script node and sensor node in VRML.The 3D reconstruction and concision of body internal organs can be formed in high quality near to those got in traditional methods.By this way,with the function of dynamic concision, VRML browser can offer better windows of man-computer interaction in real time environment than before.3D reconstruction and dynamic concision with VRML can be used to meet the requirement for the medical observation of 3D reconstruction and has a promising prospect in the fields of medical image.更多还原
