Methods: (1) four adults with an average age of three macaque monkeys accepted neck SCT scanning test. (2) Get normal macaque monkeys neck CT cross-sectional images through the flat sweep and enhanced scanning technology, volume data collection, after macaque monkey was general anesthesia. Result: good cervical artery three-dimensional reconstruction of stereo images obtained by using of CT image post-processing technology to scan the volume of data for three-dimensional image restructuring processing. This paper shows the macaque monkey neck three-dimensional restructuring image, observed macaque monkey neck vascular structure characteristics and the difference between human beings from the angle of comparative anatomy. Conclusion: three-
