title: [Micro-CT imaging research of acoustic capsule in mice].
abstract: OBJECTIVE
  To get the three-Dimensional imaging model of internal ear and middle ear using the Micro-CT equipment, and research the nondestructive imaging of mice acoustic capsule, and investigate the application of Micro-CT inmorphology of acoustic capsule.
  
  
  METHODS
  The mice were executed to harvest the acoustic capsules. The acoustic capsules were fixed in trinitrophenol before scanning by Micro-CT .Using this equipment, we obtained a 3D model of reconstruction from 2D images.
  
  
  RESULTS
  The 3D model of acoustic capsule and the model was extraordinary clear to show the eardrum, ossicles chain, vestibulum, semicircular canal, and cochlear. The 3D structure model was excellent for look through, and it was free to revolve in any axial direction on the platform of software Amira-5.4.
  
  
  CONCLUSIONS
  By using Micro-CT equipment to research the nondestructive three-Dimensional imaging of acoustic capsule, the outside structures and internal details of the acoustic capsule can be observed at the same time. 3D structure model which was good for looking through. Using Micro-CT equipment is easy to operate and also can save a lot of samples, and the images have high resolution ratio. Micro-CT has good prospects for development.
