Abstract

Mueller polarization imaging technology can fully reflect the polarization characteristics of the sample, and can be used as a method for imaging thin pathological sections of collagen tissue samples. So far, there has been no actual publication about the detection of transplanted tendons using Mueller matrix imaging technology. In this paper, we apply the Mueller imaging polarimeter for quantitative detection of rabbit transplanted tendon samples with or without tenocytes. The polar decomposition parameters of the Mueller matrix of the rabbit tendon tissues are calculated and analyzed. Quantitative analysis showed that tenocytes caused the decrease of tendon fibers retardance and the increase of standard deviation of tendon fibers orientation. The experimental results indicate that the retardance and the orientation angle parameters of the Mueller matrix can be used as quantitative indicators to distinguish rabbit tendon tissues with or without tenocytes and can reveal the structural characteristics of collagen fiber bundles, which may provide more useful information for the evaluation of tendon transplantation.
