The optical properties of a rat muscle and myocardium were measured at two wavelengths 980 and 1860 nm. The tissues used in this experiment were fresh and sliced to a specific thickness of 600 μm. A single integrating sphere system was used to determine the diffuse reflectance, diffuse transmittance, and collimated transmittance of these tissue samples. An inverse Monte Carlo algorithm was then used to calculate the optical properties from the measurements obtained from the single integrating sphere system.

We measured the reduced scattering coefficient and absorption coefficient of biological tissues of rats for 980nm and 1863nm. Results suggest potential presence of a chromophore other than water that absorbs infrared radiation in tissues.

Communication is the act of conveying a message to another person, and it is an essential skill for establishing physician-patient relationships and effective functioning among health care professionals. Participants in the Toronto Consensus meeting in the early 1990s concluded there was enough evidence to prove that doctor-patient communication problems are common and that they adversely affect patient care.1 Traditionally, most medical trainees learn verbal and nonverbal communication skills by watching their teachers and preceptors.
