Abstract
Objective determination of bruise age is still done mainly by visual inspection, however, because of insufficient information the method provides, another mode is desired. In this study, determination of bruise dynamics parameters with a four-layer model and individually determined scattering parameters was carried out. Pulsed photometric radiometry signals and diffuse reflectance spectra were recorded during the healing process for volunteers with accidental bruises. Parameters of healthy skin were obtained and used as input parameters for the bruise model. Hence, the difference in signals would be fully attributed to changes caused by the injury. Results of three bruises on the arm and the analysis of one on the outer side of the arm are presented showing bruise dynamics parameters and their dependency on bruise severity. Objective determination of bruise dynamics parameters is achieved by use of pulsed photothermal radiometry via a four-layer optical model of human skin and inverse Monte Carlo analysis with predetermined input parameters of healthy skin.
