Ultrasonic backscatter from cancellous bone: the apparent backscatter transfer function.
IEEE Trans Ultrason Ferroelectr Freq Control
December 2015
Article Synopsis
- Ultrasonic backscatter techniques are being refined to detect changes in cancellous bone due to osteoporosis, focusing on the apparent backscatter transfer function (ABTF).
- The study characterizes the ABTF across various gate delays (1 μs to 6 μs) and widths (1 μs to 6 μs) using measurements from human cancellous bone specimens in the frequency range of 1.5 to 6.0 MHz.
- Results showed that the ABTF is primarily linear with frequency, with significant changes in measurements influenced more by gate delay (τd) than by gate width (τw), impacting the correlation of measured parameters with bone density.
Ultrasonic backscatter techniques are being developed to diagnose osteoporosis. Tissues that lie between the transducer and the ultrasonically interrogated region of bone may produce errors in backscatter measurements. The goal of this study is to investigate the effects of intervening tissues on ultrasonic backscatter measurements of bone.

The backscatter-difference technique measures the power difference between two portions of an ultrasonic backscatter signal. The goal of this study is to evaluate the feasibility of using an ultrasonic imaging system to perform backscatter-difference measurements of bone.
