The severity of burns depends both on their size and depth of affected tissues. The existing simple methods for estimation of the injured skin area are not precise, especially in children. During last decades, attempts were made to employ information technologies for more precise estimation of the skin area affected by the burn. Usually, a special template («skitsa») is used to represent a human body in a schematic way, allowing automatic calculation of affected area with high accuracy. It is especially important in children, since proportions of their bodies vary greatly at different ages.A computer graphic tool for estimation of area of burns was designed for the Department of Pediatric Burns. It uses an algorithm that allows to adjust burn data displayed on a two-dimensional template, taking into account the three-dimensional nature of the human body. Such correction increases burn area estimation accuracy. Additionally, this system allows using digital photographs of burn area for dynamic assessment of skin condition during treatment. A special algorithm is used to compensate for possible color distortions of the photographs in series, enabling better possibility of patient’s skin condition comparison at different times.
