Over 10% of women experience levator ani muscle (LAM) injuries during childbirth. Yet, the limited knowledge of LAM physiopathology restricts progress in prevention, diagnosis, and treatment. Shear wave elastography (SWE), an ultrasound technique for quantifying tissue elasticity, offers potential for detecting related mechanical changes. However, its clinical application is constrained by isotropy assumptions, which do not hold true for the anisotropic LAM. This study aims to develop LAM phantoms with varied mechanical properties and investigate rotational SWE to assess changes in shear anisotropy. Four phantoms mimicking the puborectalis fiber network were made using high-and low-density nylon or polyethylene (PE) fibers in a polyvinyl alcohol hydrogel, subjected to one or two freeze-thaw cycles. An additional phantom with combined puborectalis-pubococcygeus fiber networks was created to compare with the similar phantom with isolated puborectalis fibers. Using a Verasonics V1 system and a custom rotational setup, shear wave velocities were estimated by applying the Radon transform to axial velocity maps and fitting the results to an elliptical model. The rotational SWE imaging allowed to distinguish phantoms mimicking different physiopathological states and age groups. High-density nylon phantoms with one or two freeze-thaw cycles reflected LAM at rest or stretched states as well as elasticity differences related to delivery mode. The low-density nylon phantom showed reduced anisotropy, suggesting overdistension, while the PE phantom exhibited higher anisotropy and elasticity, resembling a contracted LAM in younger women. The combined puborectalis-pubococcygeus phantom further showed that adjacent fiber networks affected shear wave propagation, reducing signal quality and altering shear properties. Despite limitations on phantom construction, these findings support in-vivo research into LAM pathophysiology using SWE.
