大鼠下丘脑部分核团形态学的测量及计算机三维重建

目的：系统地反映下丘脑有关核团的立体模式,为深入探讨下丘脑的功能提供形态学依据。方法：制作正常成年SD大鼠冷冻冠状连续切片,运用MAPGIS 6．0测量下丘脑弓状核、室旁核、腹内侧核、背内侧核的截面积、体积等相关数据,并用3DS MAX 5．0软件三维重建出下丘脑及核团的立体图像。结果：三维重建的立体图像逼真自然,能够流畅地旋转、缩放,可在任一角度观察其形态,任一平面切割行切面观察,图像空间毗邻及定位准确,三维测量获得了精确的解剖参数。结论：下丘脑及核团的计算机重建图像可从多个外科手术角度进行观察,为脑的立体定向研究及颅部外科手术提供重要参考资料。

Morphological measurment and computerized three-dimensional reconstruction of rat hypothalamic nucleus

Objevtive:To systematically understand the three-dimensional mode of the hypothalamic nucleus,pro- viding morphological data for approaching hypothalamic function.Methods:The hypothalamic nuclei were studied by computer 3D reconstruction technique after the serial coronal sections of the healthy adult SD rat brain was ex- amined.Their images were depicted and recognized,and were reconstructed by using 3DS MAX 5.0.By means of MAPGIS 6.0,the average area and volume of hypothalamic nucleus was measured.Results:The reconstructed hypothalamic nuclei were smooth,natural and realistic,which were observed in all directions.The image could be rotated,zoomed and cut in any direction.Conclusion:The reconstructed images of the hypothalamic nucleus can be viewed from all surgical angles and the spatial relationship can be accurately measured,providing some guidance for the brain surgery.
