Abstract :
Optic visualization of auricular blood vessels is considered using transillumination. Since the vessels and nerves course alongside one another, the locations of the nerves are disclosed. The visualization of the nerves is needed for a precise needle application by physician within the scope of electrical stimulation of auricular nerves; the stimulation being applied for pain relieve. Theoretical approaches are considered based on light absorption coefficients over wavelength of different auricular tissue types, which predict optimal optical contrasts for green and blue light. Complementary experimental approaches are introduced which statistical results have proved theoretical reasoning.
