Abstract

The influences of dehydration and thermal damage on in υitro optical properties of human aorta were studied. The absorption coefficient increased by 20–50%, especially in the visible range when at least 40% of total tissue weight was lost as a result of dehydration. The reduced scattering coefficient increased by 10–45% in the visible and 30% to over 150% in the near IR after the tissue samples were heated in a constant temperature water bath at 100°C for 300 ± 10 s. This study implies that dehydration and protein coagulation during photothermal treatment of tissue are important factors altering optical properties of tissue.
