“…Biological tissue is an aggregate of similar cells and cell products (tissue fibres and gels) forming a definite kind of structural material in normal or abnormal state [47, 51,[66][67][68][69][70][71][72][73][74][75][76]. There are three major types of tissues, such as epithelial, connective, and glandular.…”

Abstract. This is the first section of the review--tutorial paper describing fundamentals of tissue optics and photonics mostly devoted to biological tissue structures and their specificity related to light interactions at its propagation in tissues. The next sections of the paper will describe light--tissue interactions caused by tissue dispersion, scattering, and absorption properties, including light reflection and refraction, absorption, elastic quasi--elastic and inelastic scattering. The major tissue absorbers and types of elastic scattering, including Rayleigh and Mie scattering, will be presented. © 2015 Samara State Aerospace University (SSAU).Keywords: biophotonics; tissue optics; tissue structures.

“…The complex¯ber structure causes a strong light scattering of the myocardium. [44][45][46][47][48][49] Refractive index values measured for human and bovine myocardium tissue, 3,50 porcine 51-55 and human skeletal muscle tissue 56 are summarized in Table 1. Since the values are very close to each other and weakly dependent on the wavelength in the range under study (600-900 nm), in this paper we assume the average value of refractive index of myocardium tissue as 1:376 AE 0:007.…”

The results on determination of glucose and glycerol di®usion coe±cients in myocardium tissue are presented. The method is based on the measurement and analysis of temporal dependence of tissue optical collimated transmittance under action of a hyperosmotic agent. This temporal tissue response is related to the rate of the agent and water di®usion in a tissue. The di®usion coe±cients for tissue°uid°uxes at glucose and glycerol application to the myocardium at 20 C have been estimated as ð4:75 AE 3:40Þ Â 10 À7 and ð7:71 AE 4:63Þ Â 10 À7 cm 2 /s, respectively.

(1) Background: Microwave ablation (MWA) is a common tumor ablation surgery. Because of the high temperature of the ablation antenna, it is strongly destructive to surrounding vital tissues, resulting in high professional requirements for clinicians. The method used to carry out temperature observation and damage prediction in MWA is significant; (2) Methods: This work employs numerical study to explore temperature distribution of typical tissues in MWA. Firstly, clinical MWA based on isolated biological tissue is implemented. Then, the Pennes models and microwave radiation physics are established based on experimental parameters and existing related research. Initial values and boundary conditions are adjusted to better meet the real clinical materials and experimental conditions. Finally, clinical MWA data test this model. On the premise that the model is matched with clinical MWA, fat and bone are deduced for further heat transfer analysis. (3) Results: Numerical study obtains the temperature distribution of biological tissue in MWA. It observes the heat transfer law of ablation antenna in biological tissue. Additionally, combined with temperature threshold, it generates thermal damage of biological tissues and predicts the possible risks in MWA; (4) Conclusions: This work proposes a numerical study of typical biological tissues. It provides a new theoretical basis for clinically thermal ablation surgery.
