Abstract

Abstract: The quantitative ultrasound technique was used to evaluate bone-mimicking phantoms; however, these phantoms do not mimic the intermediate stages of cortical bone healing. We propose using windshield glass as an original material to produce phantoms that mimic the characteristics of three different stages of cortical bone healing. This material was processed via a route that included breaking, grinding, compacting, drying, and sintering in four temperature groups: 625 °C, 645 °C, 657 °C, and 663 °C. The parameters evaluated were the ultrasonic longitudinal phase velocity ( c L ), corrected ( α c ) ultrasonic attenuation coefficient, and bulk density ( ρ s ). The results showed that the mean values of c L, α c, and ρ s varied from 2, 398 to 4, 406 m·s −1, 3 to 10 dB·cm −1, and 1, 563 to 2, 089 kg·m −3, respectively. The phantoms exhibited properties comparable with the three stages of cortical bone healing and can be employed in diagnostic and therapeutic studies using ultrasound.
