具有较高的分辨率Objective: On the basis of displaying sectional images

reconstruction and cutting of the human body were done using a three dimensional (3D) reconstruction software in computer for revealing the anatomic structure of Fengfu (GV 16) from different layers. Methods: A formalin fixed male corpse (2 years) was used in this study. ABS fluid mixed with scarlet dye was used for arterial perfusion to display large blood vessels. After locating Fengfu (GV 16) according to the national standards of acupoints and freezing the body (-30 ℃)

a hole was made along GV 16 to the routinely used depth using a high speed bit

and then filled with red plasticine for displaying different cross sections of the acupoint. The frozen sample was then put into a wooden box which was filled with water to be frozen again

and was cut into less than 2 mm thick sections with a high speed steel plane machine

photographed and videotaped. The collected images were fed into a computer and reconstructed into facade and dorsal pictures with 3D reconstruction software

on the basis of which

sagittal

coronal and horizontal plane cutting of the body were carried out. Results: 200 pieces of reconstructed pictures of Fengfu (GV 16) were obtained. From the reconstructed sagittal plane and coronal plane images of GV 16 the blood vessels

muscular tissues

etc. could be seen distinctly. Additionally

other structures were also shown clearly. For example

the sagittal pictures of Fengfu (GV 16) distinctly displayed the appearance of the brain

cerebellum and the spinal cord. On the coronal plane

the images of GV 16 showed the fascia and muscle tissues. From the horizontal plane images

the appearance of the bottom of the cerebellar hemisphere

medulla oblongata

the head semispinal muscle

etc could be seen. Images of the oblique plane

the head splenius muscle (on one side of GV 16) and the head semispinal muscle (deep layer) could be seen. Conclusion: The reconstructed pictures of Fengfu (GV 16) from the entity images with the software show the clear structures

which has the bright color and satisfactory resolving power.
