Paper Abstract

We acquired polarized reflectance images and Mueller matrix of fresh bovine skeletal muscle. Using polarization-dependent Monte Carlo simulations based on a sphere-cylinder scattering model, we are able to reproduce the characteristic features in the experiment results. We also simulate the changes of reflectance profile during stretching and rigor process, which are regarded as the changes of cylinders' diameter and the cylinder-sphere ratio in our model. The good agreement between simulations and experiments indicates that the unique pattern of polarized reflectance of skeletal muscles can also be due to scattering of well aligned fibrous myofibrils rather than coherent diffraction on the sarcomeres. It provides another angle to understand the interaction between photons and skeletal muscle and a proper model which characterizes the microstructure of the skeletal muscle. In addition, we give a parameter K calculated from the M12 element of Mueller matrix. The K-value is sensitive to different parameters in sphere-cylinder scattering model, therefore it is expected to use for monitoring the states of the skeletal muscle.
