Method for Estimating Bone Structure of Proximal Femur by Using Ultrasonic Attenuation and Backscatter Coefficients

摘要

The present invention relates to a method and apparatus for predicting a femoral bone structure using an ultrasonic attenuation coefficient and a backscattering coefficient, and a method of predicting a bone structure using an ultrasonic attenuation coefficient and a backscattering coefficient includes the steps of irradiating an ultrasonic pulse to the femur; A converting step of receiving ultrasonic pulses reflected from the femur and converting the ultrasonic pulses into electrical signals; And calculating a bone volume fraction (BV / TV) and a spongy bone thickness (Tb.Th) by calculating an ultrasound attenuation coefficient and a back scattering coefficient through the electrical signal converted in the conversion step And a technique for calculating the bone structure of the femur. According to the present invention, the ultrasonic attenuation coefficient and the back scattering coefficient are calculated by irradiating ultrasonic waves to the femur and receiving the ultrasonic waves reflected from the femur to calculate a correlation between the bone volume fraction (BV / TV) and the spongy bone thickness (Tb.Th) It is possible to predict the bone structure of the femur.
