Parameter | Fluence* (J/cm2) | HbO2 molar extinction (cm−1mM−1) | Hb molar extinction (cm−1mM−1) | HbO2 absorption coefficient** (mm−1) | Hb absorption coefficient** (mm−1) |
---|---|---|---|---|---|
765 nm | Φ01 = 0.043 | αo1 = 0.616 | αd1 = 1.435 | µao1 = 0.11 | µad1 = 0.25 |
800 nm | Φ02 = 0.096 | αo2 = 0.816 | αd2 = 0.762 | µao2 = 0.14 | µad2 = 0.13 |
*Calculated using half period of modulation of laser excitation light τ = 0.012 second
**Calculated suggesting SaO2 = 100% for HbO2 and SaO2 = 0% for Hb and using typical concentration of hemoglobin in porcine blood THb = 1.77 mM (11.4 g/dL, hemoglobin molecular weight MW = 64500 g/mole) [30].
