abstract = {In this work, we present a novel preclinical device utilizing Torsional Wave Elastography (TWE). It
comprises a rotational actuator element and a piezoceramic receiver ring circumferentially aligned.
Both allow the transmission of shear waves that interact with the tissue before being received. Our
main objective is to demonstrate and characterize the reliability, robustness, and accuracy of the
device for characterizing the stiffness of elastic materials and soft tissues. Experimental tests are
performed using two sets of tissue mimicking phantoms. The first set consists of calibrated CIRS gels
with known stiffness value, while the second test uses non-calibrated manufactured phantoms. Our
experimental observations show that the proposed device consistently and repeatably quantifies the
stiffness of elastic materials with high accuracy. Furthermore, comparison with established techniques
demonstrates a very high correlation (> 95%), supporting the potential medical application of this
technology. The results obtained pave the way for a cross-sectional study aiming to investigate the
correlation between gestational age and cervical elastic properties during pregnancy.},
