摘　　要：利用数学形态学对含有胎儿头部轮廓的医学图像进行预处理,提取近似圆形的胎儿大脑轮廓的骨架。利用hough变换自动逼近,获得最逼近胎儿大脑轮廓的圆周,此圆周的直径可以近似双顶径。Medical Images including head outline are preprocessed by using mathematical morphology, and the skeleton of fetus＇ head outline with an approximate rotundity can be extracted. The circle of head outline is automatically obtained by hough transform, and its diameter is approximately equal to the biparietal diameter.

关 键 词：数学形态学 HOUGH变换 双顶径
