Comparison between Cylindrical, Trigonal, and General Symmetry Models for the Analysis of Polarization-Dependent Second Harmonic Generation Measurements Acquired from Collagen-Rich Equine Pericardium Samples

Abstract: Polarization-dependent second harmonic generation (PSHG) microscopy is used as an innovative, high-resolution, non-destructive, and label-free diagnostic imaging tool to elucidate biological issues with high significance. In the present study, information on the structure and directionality of collagen fibers in equine pericardium tissue was collected using PSHG imaging measurements. In an effort to acquire precise results, three different mathematical models (cylindrical, trigonal, and general) were applied t… Show more

“…Collagen structural parameters modeling is usually done by performing an approximation of a cylindrical symmetry for the collagen fiber [1,2]. Such approximation has shown its limitations in numerous situations [4]. To overcome these limitations, a trigonal symmetry approximation can be used instead of a cylindrical symmetry [4].…”

“…Such approximation has shown its limitations in numerous situations [4]. To overcome these limitations, a trigonal symmetry approximation can be used instead of a cylindrical symmetry [4]. In any cases, assuming a cylindrical or a trigonal symmetry is a case-dependent procedure which is difficult to generalize to a systematic and generic study of collagen alteration during tumorigenesis.…”
