[Application of ultrasonic microscopy in biomechanical properties measurement of cancellous bone].
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.
