Science Letters:Dynamic concision for three-dimensional reconstruction of human organ built with virtual reality modelling language (VRML)

This research studies the process of 3D reconstruction and dynamic concision based on 2D medical digital images using virtual reality modelling language (VRML) and JavaScript language, with a focus on how to realize the dynamic concision of 3D medical model with script node and sensor node in VRML. The 3D reconstruction and concision of body internal organs can be built with such high quality that they are better than those obtained from the traditional methods. With the function of dynamic concision, the VRML browser can offer better windows for man-computer interaction in real-time environment than ever before. 3D reconstruction and dynamic concision with VRML can be used to meet the requirement for the medical observation of 3D reconstruction and have a promising prospect in the fields of medical imaging.

集成图像空间分辨率研究

从集成图像显示时再现的空间光学分布着手,研究了微透镜参数、记录/显示平面分辨率和成像系统空间分辨率的关系。研究结果表明成像系统的空间分辨率与微透镜的孔径和焦距大小有关。采用较小尺寸的微透镜,有助于提高成像系统的空间分辨率,但对记录/显示平面分辨率的要求随微透镜尺寸的减小以及物点深度的增加而提高。研究结果可用于集成成像系统的优化设计。
