Abstract:

Objective　To investigate the simple spacial 3ds Max model reconstructing  orthotopic and heterotopic kidney transplantation in rat.　Methods　Based on the anatomic structures of rat, the following organs, such as kidney, adrenal gland，blood vessel, bladder, airtubs and glandula thyreoidea were reconstructed using the commands of loft, boolean controler, poly select, bevel profile, lethe et al. Those virtual organs were then merged into the abdomen and neck scenes, at the same time, installed free camera was used to get 3D images after rendering.　Results　 Organs related with kidney transplanation were reconstructed and simulated the scenes in situ，right iliac fossa as well as anterior site of neck successfully, which can provide reliable references for improving surgery effects of animal operation.　Conclusions　The 3D model building methods of non geometric shape organs and scenes of 3ds Max have the advantages of repeatibility and easy to perform in personal computer.
