三维结构与体视学

Three-dimensional structures and stereology

基于2012—2013体视学学科发展报告项目和中国体视学学会组织的集体研讨,本文回顾了在体视学(stereology)发展过程中其定义的多样化,探讨了体视学的学科基本特征,进而对体视学的定义与内涵提出新的建议。体视学是不断发展中的研究三维结构的交叉学科和方法学,同时包括基于低维截面或投影数据对三维结构表征参量的统计性推估与结构的三维重建。从投影数据重建三维CT图像属于体视学研究范畴;针对维数大于3的高维结构(三维几何结构+时间维或其他维)开展体视学理论与方法研究亦很有必要。目前体视学已形成了坚实的理论与方法体系,同时又进入了一个不同方法相互补充、借鉴和协同融合发展的新阶段,有着光明的发展和应用前景。不断推广应用体视学与研究发展体视学新方法仍然是我们面临的两大主题。

Abstract： Based on the primary results derived from Project of ＂2012--2013 Report on Advances in Ster- eology＂ and related activities organized by Chinese Society for Stereology,various definitions of stereology were first reviewed and the related discipline characteristics were discussed, some new suggestions were proposed for the definition and connotation of stereology. Stereology is a new developing interdiscipli-nary science and methodology to study three-dimensional structures, including both the determination of statistical characterization parameters and the reconstruction of the three-dimensional structures based on the data obtained from lower-dimensio~：~〈 The computed tomography theories and technology on the three-dimensional reconstruction of images from projection data fall into the scope of stereology. It is also necessary to explore possible stereological theories and methodology on those structures with their dimen- sionality higher than 3 （geometric dimensionality already formed its own solid theory system and plus other dimensionality such as time）. Stereology has methodology,is continuously developing by complement each other and collaborative development of different methods, and has a very bright prospective. Both promoting applications of stereology and further developing new stereology methods remain our two main themes.
