Fig. 3. Author’s laboratory-built NIRAF imaging system to identify parathyroid glands. When NIR light (785 nm) is illuminated to the surgical field (short arrow), the 822 nm of NIRAF is emitted from the fluorophore of parathyroid gland (long arrow) and then the camera detects the NIRAF. No need to use any exogenous contrast dye during the procedure (NIRAF, near-infrared autofluorescence).
