Abstract: Objective Observing rhesus monkey big vascular system of chest by 256 layer spiral CT and providing scientific materials for studying rhesus monkey vascular and digitization system. Methods Five male and five female rhesus monkeys aging at 6 to 10 years old were selected and obtained for CT scanning experiment. Rhesus monkey chest CT cross-sectional images were acquired through flat and strengthen scanning technique to collect volume data. Rhesus monkey volume data were processed by 3D image restruction using CT image post-processing technology. Results Rhesus monkey stereoscopic images of aorta, pulmonary artery and vein and chest big vascular were obtained by Three-dimensional reconstruction. From the point of comparative anatomy the difference of chest big vascular system between rhesus monkey and human being were found. Conclusion The anatomical and tissue structures of rhesus monkey among the big vascular system were reflected perfectly by Three-dimensional CT reconstruction. It is an effective, non-invasive and direct ideal way of observation of the vascular system.
