Objective To research the clinical diagnosis of lung disease in rhesus monkey with the observation of lung CT tomography of the adult laboratorial rhesus monkey，to establish the maps of CT tomography of the healthy adult rhesus monkey，to provide the basic image data of CT technology in the applications of anatomy，clinical diagnosis and scientific experiments of rhesus monkey． Methods 5 male and 5 female health adult monkeys aged 5 ～ 10 years were selected for this study of lung CT tomography after being checked by palpation，percussion，auscultation and by examination of body temperature，respiratory rate，heart rate，breathing motion and blood parameters． After general anesthesia，the monkeys were placed on the table-board of CT in supine position and were scanned to get the image of lung CT tomography．The main structure of every level in scanned images were labeled，such as lobe，trachea，arteries and veins，etc． Results ( 1) 13 anatomical images of lung CT tomography are obtained． ( 2) In the image of CT tomography，lung，trachea，large blood vessels are all in focus． Lungs are composed of the right part and the left part，the left lung is divided into upper lobe，middle lobe and lower lobe． Right lung is divided into upper lobe，middle lobe，lower lobe and azygos lobe． Left main bronchus，right main bronchus，bronchial and vascular are very obvious in different scanned images． ( 3) Interfaces of small blood vessels，small nerves and muscle tissues are not clearly defined on the CT scanned images． Conclusions ( 1) The images of lung CT tomography of the healthy adult rhesus monkey show that all the lung lobes are absolutely clear，lung transmittance is good，and there are no any shadows． ( 2) Obtained the anatomy CT tomography image data of healthy adult rhesus monkey． It can provide a new safe，convenient and accurate basis for diagnosis of monkey lung disease． It also established the background Information data of CT tomography anatomy of the healthy adult rhesus monkey．
