Pulsed photothermal radiometry of human artery

Pulsed photothermal radiometry of human artery

Pulsed photothermal radiometry (PPTR) has been used to measure, in vitro, the optical attenuation coefficients of normal and diseased human artery at four wavelengths (308, 351, 488, 532 nm) in the near UV and visible spectrum. The advantages and limitations of this noncontact method of measuring th...

Zusammenfassung:Pulsed photothermal radiometry (PPTR) has been used to measure, in vitro, the optical attenuation coefficients of normal and diseased human artery at four wavelengths (308, 351, 488, 532 nm) in the near UV and visible spectrum. The advantages and limitations of this noncontact method of measuring the optical properties of biological material, as well as other potential applications, are discussed.
