Optical control of mesh implants

Complex investigation of mesh implants was performed involving laser confocal microscopy, backscattered probing and OCT imaging methods. The applicability limits of differential backscattering for monitoring the post-operation state of mesh implant and adjacent tissues are established based on model numerical experiments. The possibility of detecting the optical inhomogeneities associated with pathological tissues alteration near the surface of implant fibers is shown. The applicability of OCT imaging for mesh implant control was demonstrated. Special two-stage OCT image noise-reduction algorithm, including empirical mode decomposition, was proposed. It was validated that proposed method highly improve single-to-noise ratio and make it possible to use OCT imaging for mesh implant control.
