Optimization of surgical field illumination to maximize the contrast when biological objects being visualized

Experimental technique and devices

The optimal lighting conditions for contrast imaging of biological tissues during surgical operations have been studied. In so doing a special experimental setup based on a dynamically controlled led lighting system was used. The operating team selected the optimal illumination of the operating field during work with individual organs and tissues of animals (rats); simultaneously experimental investigations of the spectral characteristics of these biological objects were carried out. Relying on such experimental data, an analysis of luminance and color contrasts, including a comparison with a halogen lamp effect. According to results of studies the need to use special lighting with optimization of its intensity and a wavelength spectrum was confirmed. Such a measure will increase the contrast during surgical operations.
