“…5 and 7. However, since the birefringence of tissues can also be originated from the well aligned cylindrical scatterers [34], we carry on further simulations using the sphere-cylinder scattering model (SCSM) which does not include the birefringent interstitial medium. For the MC simulated results of SCSM shown in Fig.…”

Abstract:In this paper, we take the transmission 3 × 3 linear polarization Mueller matrix images of the unstained thin slices of human cervical and thyroid cancer tissues, and analyze their multispectral behavior using the Mueller matrix transformation (MMT) parameters. The experimental results show that for both cervical and thyroid cancerous tissues, the characteristic features of multispectral transmitted MMT parameters can be used to distinguish the normal and abnormal areas. Moreover, Monte Carlo simulations based on the sphere-cylinder birefringence model (SCBM) provide additional information of the relations between the characteristic spectral features of the MMT parameters and the microstructures of the tissues. Comparisons between the experimental and simulated data confirm that the contrast mechanism of the transmission MMT imaging for cancer detection is the breaking down of birefringent normal tissues for cervical cancer, or the formation of birefringent surrounding structures accompanying the inflammatory reaction for thyroid cancer. It is also testified that, the characteristic spectral features of polarization imaging techniques can provide more detailed microstructural information of tissues for diagnosis applications. properties and effect of wavelength choice on differentiation between ex vivo normal and cancerous gastric samples," J.

“…It is known that spherical scatterers contribute only to depolarization, not to diattenuation and retardance. 26 We apply 4 × 4 and 3 × 3 decomposition methods to the experimental and simulated Mueller matrices for the spheres with different scattering coefficients and sizes, as shown in Figs. 4(a)-4(c).…”

Abstract. Using Monte Carlo simulations based on previously developed scattering models consisting of spherical and cylindrical scatterers imbedded in birefringent interstitial medium, we compare the polarization parameters extracted from the 3 × 3 and 4 × 4 Mueller matrix decomposition methods in forward and backward scattering directions. The results show that the parameters derived from the 3 × 3 Mueller matrix decomposition are usually not the same as those from the 4 × 4 Mueller matrix decomposition but display similar qualitative relations to changes in the microstructure of the sample, such as the density, size, and orientation distributions of the scatterers, and birefringence of the interstitial medium. The simulations are backed up by experiments when suitable samples are available.

“…[1][2][3] In a recent study, 4 we showed that scattering by well-aligned cylindrical scatterers displayed anisotropic effects, including a retardance that was similar to that of a piece of birefringent media whose extraordinary axis, and the fast axis, was along the axial direction of the aligned cylinders. We also examined the different contributions to the polarization features provided by the well-aligned cylindrical scatterers and the anisotropic interstitial medium.…”

“…[4][5][6][7]13 The diameter and density of the spherical and cylindrical scatters, the degree of the alignment and spatial orientation of the cylindrical scatters, the optical properties of the scatterers, and the interstitial media were all variables used in the simulations to mimic the properties of turbid media such as tissues. …”

Abstract. Both cylindrical scatterers and birefringent media may contribute to the anisotropy of tissue, where anisotropy can be characterized using polarization techniques. Our previous studies have shown that a layer of well-aligned cylindrical scatterers displays anisotropic properties similar to those of a piece of birefringent media, whose equivalent extraordinary axis is along the axial direction of the cylinders. We focused on a sample consisting of two layers of anisotropic media, with each layer having a different orientation; the characteristics of this sample were representative of the properties of multilayer fibrous tissues. Using a Mueller matrix decomposition method, we examined in detail how the total retardance and the equivalent extraordinary axis of the bilayered sample varied with changes in the retardance of the two layers and the direction of the extraordinary axis. The results of this study showed that, in such bilayer samples, a layer of well-aligned cylindrical scatterers generated a retardance that behaved exactly like the retardance generated by a piece of birefringent media. The simulated results were also confirmed by the results of experiments using aligned glass fibers. © The Authors. Published by SPIE under a Creative Commons Attribution 3.0 Unported License.
