Abstract:
Apparent Integrated Backscattering (AIB) presents correlation between Apparent Backscatter Transfer Function and the transducer bandwidth. Replicas of trabecular bones (cubes of 20 mm side length) created by 3D printing technique were characterized using AIB with a 2.25 MHz center frequency transducer. A mechanical scanning system was used to acquire multiple backscatter signals. An uncertainty model in measurement based on the Guide to the Expression of Uncertainty in Measurement was proposed. Initial AIB results are not metrologically reliable, presenting high measurement uncertainties (AIB = -15.1 dB ± 13.9 dB). It is noteworthy that the uncertainty model proposed contributes for metrological assessment of trabecular bone characterization using AIB.
