title: [Application of ultrasonic microscopy in biomechanical properties measurement of cancellous bone].
abstract: OBJECTIVE
  Ultrasound scanning can provide the information of acoustic impedance through the ultrasonic reflection theory. This study tries to introduce the application of the ultrasonic technique in predicting biomechanical properties of cancellous bone.
  
  
  METHODS
  The rat femoral head embedded in plexiglass was used as the bone specimens for ultrasound scanning and the gray scale images scanned by ultrasound microscope were collected and analyzed.
  
  
  RESULTS
  The value of acoustic impedance was calculated by analyzing the gray scale image.
  
  
  CONCLUSIONS
  The application of ultrasonic microscopy can show more value about the microstructure of biomechanical properties of bone tissue.
