Hello
Please help me on these questions. Thank you! Question 1 A tissue with a total attenuation coefficient of 110 cm -1 at wavelength 550 nm has an SO2 of 55% and a total hemoglobin concentration 20 uM 1.a. What are the concentrations of deoxy and oxygenated hemoglobin? 1.b. What is ua(550nm) due to blood in this tissue? 1.c. What is Ho(550nm) for water? Hint: estimate from the tables provided in the lecture ppts. 1.d. Assuming that blood and water are the only two absorbers in the tissue, what is the scattering coefficient, .(550nm)? 1.e. List some tissue components known to scatter light. List at least 4. 1.f. Draw the wavelength dependence of the scattering coefficient in tissue from ~300-800 nm.

Explanation / Answer

A The concentration of oxy will be five times the deoxy

E skin , brain , vessel walls are used to scatter light (epithelial tissue)

D coefficient will be 20g
