Abstract: Objective To establish the method of using the atlas morphological indexes for sex determination in Jilin province and to evaluate its effect.
Methods The clinic neck CT images were used to reconstruct the 3D image of atlas.A total of 27 linear measurements on 8
aspects of the atlas were measured and the ratios were calculated.The 14 items were selected.Results Of the total 27 linear measurements,14 were sexually dimorphic（P<0.05）,and the accuracies of sex determination of 27 indexes were 52.0%-89.3%.The highest accuracy was width of vertebral body(
 86.7%).A function with variables predicting sex with 95.8% accuracy was derived by using stepwise method of discriminant function analysis:Y=1.308W－0.409CDF－0.469LTPSD－0.849LUACD+0.478RUACD+0.332RDACD+0.363ATH－0.334PTH－0.236PAL.Conclusion
The method of using atlas traits for sex determination in Jilin province  is practicable.

Key words: three dimensional reconstruction, atlas, sex　determination
