Review Questions

• How do the concepts of absorption and scattering contribute to our understanding of tissue optics?
  • Absorption and scattering are two key processes that describe how light interacts with biological tissues. Absorption refers to the amount of light energy converted into other forms when it enters a tissue, while scattering describes how light changes direction when it hits particles within the tissue. Understanding these processes allows researchers to characterize the optical properties of different tissues, which is vital for developing diagnostic tools and treatment methods that rely on accurate imaging and light manipulation.
• Discuss the role of Monte Carlo simulations in studying tissue optics and their significance in predicting light transport.
  • Monte Carlo simulations are a powerful tool used to model how light travels through complex biological tissues.
