摘要
本文研究了胎儿肠道神经细胞(胞体)群体连续切片图象的计算机三维重建及显示。首次利用行程编码压缩离散群体的三维重建数据,以降低对计算机内存的需求及提高三维重建速度。在截面重建法的基础上,引入仿射变换作为旋转、投影变换,以实现不同角度观察细胞群体的三维空间结构及形状。理论分析和实验研究均表明:本文的方法能在微机上同时实现多个细胞体的三维重建及显示。最后展示了一些不同角度的胎儿肠道神经元胞体的重建显示结果图象并进行了讨论。
<ABSTRACT>
This paper studied tri-dimensional (3D ) reconstruction and display
of fetal intestinal neurons from series slices. Data of reconstruction of
the neurons were compressed by run-length coding to decrease the need
of computer memory with increase of speed of 3D reconstruction. In or-
der to observe 3D structure of the neurons from different angles, affine
transformation was used as ration and projection transformation using
section reconstruction technique. Experimental results and theoretical ana-
lysis showed that the neurons could be reconstructed at once in microcom-
puter. Some of the reconstructed photomicrographs were showed in the
