“…The experiment results about birefringence of the chicken muscle in the process of dehydration and hydrolysis have been published by us [9] , shown in fig.7 [9] , in which fig.7(a) is figure of birefringence with time of dehydration and fig.7 fig.9. We can see that the fluctuation of the integral reflectivity can be separated to two stages, rising in the first 6 hours, and then falling.…”

“…And changes in birefringence can be used to indicate changes in functionality, structure, or viability of tissues in the early stages of disease [1] . Muscle is a biological tissue with obvious birefringence [5,6] , and muscle birefringence is not only related to the muscle microscopic structure but also the surrounding physical, chemical and biological environments, so the change of muscle birefringence can indicate many information of tissue such as physical function, metabolism and pathological changes, and until now there have been many investigations on it using PS-OCT, such as muscle contraction mechanism by M. Peckham [7] , and exercised-induced skeletal muscle damage by James J. Pasquesi [8] , and muscle dehydration and proteolysis by Yang Lifeng [9] . In this paper we focus on investigation of muscle stretching and damage by PS-OCT, first we obtain two-dimensional cross-sectional images of muscle in the different states of stretching and damage, and by analysis of the experiment data we mainly extracts parameters including extinction coefficients, integral reflectivity, and birefringence to characterize muscle changes, next we use our polarization-sensitive sphere plus cylinder plus birefringence Monte Carlo program [10,11] to simulate the two processes in order to explore further and verify the regularities between optical parameters and muscle states.…”

In this paper, we study muscle elastic drawing and damage using our lab's polarization-sensitive optical coherence tomography (PS-OCT) instrument and polarization sensitive Monte Carlo program. First, we acquire two-dimensional PS-OCT images of elastically drawn and injured muscle, injury processes including dehydration and hydrolysis, we extract some characteristics from experimental results including extinction coefficient, integral reflectivity and birefringence and so on, which will change during muscle is being elastically drawn or injured. In order to further understand and evaluate the degree of muscle elastic drawing or damage according to the measurements parameters mentioned above, we do some corresponding simulations using our lab's Monte Carlo program, which is based on a sphere cylinder birefringence model and can simulate complicated tissue containing anisotropic microstructures and various polarization imaging and measurement systems. For muscle elastic drawing, we find that integral reflectivity sometimes increases and decreases as muscle's elastic drawing continues, and through simulation we are unable to find the relationship between extinction coefficients and muscle elastic drawing. As for muscle damage, we simulate two processes: dehydration and hydrolysis. We find that as dehydration deepens, the birefringence of muscle is increasing but getting slowly and the integral reflectivity is decreasing, and as hydrolysis deepens, the birefringence decreases and the integral reflectivity decreases almost linearly. Through the analysis above, we demonstrate the validity of those parameters to characterize muscle elasticity and fiber structure and explain its potential for assessment of muscle damage.

Mueller matrix polarization imaging and quantitative parameters analysis method

2023

View full text Add to dashboard Cite

Mueller matrix polarization imaging is a new biomedical optical imaging method that can generate both polarization and isotropic intensity images of structures of the biological tissue sample surface. In this paper, a Mueller polarization imaging system in the reflection mode is described for obtaining the Mueller matrix of the specimens. Diattenuation, phase retardation, and depolarization of the specimens are derived by using the conventional Mueller matrix polarization decomposition method and a newly proposed direct method. The results show that the direct method is more convenient and faster than the conventional decomposition method. The polarization parameter combination method is then presented in which any two of the diattenuation, phase retardation, and depolarization parameters are combined, and three new quantitative parameters are defined in order to reveal more detailed anisotropic structures. The images of in vitro samples are presented to demonstrate the capability of the parameters introduced.
