ABSTRACT

The study of optical properties of biological tissues is an important objective for development of advanced optical methods in medicine.
In this report we present results of in vitro study of the optical properties of the rat pancreas in the normal state (10 samples) and after development of pancreatitis (10 samples). The pancreatitis has been modeled in vivo by local ischemia of the great vessels.
Diffuse reflectance, total and collimated transmittance of the pancreas have been measured with the commercially available LAMBDA 950 spectrophotometer (Perkin Elmer, USA) in the wavelength range 350-2500 nm. Absorption coefficient, scattering coefficient, and anisotropy factor have been calculated using the inverse Monte Carlo method.
