a Three orthogonal plan views of ABUS imaging of the Ultrapro™ Mesh box, while b is HHUS imaging result (axial plane). Note that fragment No. ➀ is parallel to the horizontal plane, fragment No. ➁ is rotated a certain angle in the horizontal plane, fragment No. ➂ is rotated a certain space angle in the depth direction of the horizontal plane, and fragment No. ➃ is curved to represent the shrinkage of the mesh. Note that the fragments No. ➀–➃—are used to simulate the mesh spatial variation that may occur after implantation.
