Paper accepted in Ultrasound in Medicine & Biology

A joint paper with Prof. John Barker and Dr. Bhavsar from the Frankfurt Initiative for Regenerative Medicine has been accepted for publication in Ultrasound in Medicine & Biology.



The most common imaging method used to monitor bone fracture healing is multiple radiographic images performed by highly trained professionals with expensive equipment that can expose patients to high levels of ionizing radiation. Here we introduce and demonstrate proof-of-concept of a potential alternative method for measuring bone fractures – ultrasound pitch-catch measurement technique. Measurements are performed with 2 piezoelectric transducers, housed in standard orthopedic screws, fixed on either side of simulated fractures, with and without an orthopedic plate, in ex-vivo pig limb bones. Using this measurement method, we were able to detect significant differences between uncut, 2, 5, and 10mm deep bone cuts using a two-sided t-test with an alpha-level of 5%.
