Optical technologies of local positioning in healthcare (an analytic review)

Local positioning is the determination of the location of moving objects in a closed space in real-time. The use of indoor-positioning systems as part of telemedicine systems will make it possible to quickly locate the patient's location in cases where his vital signs deteriorate sharply and promptly provide him with the necessary medical care. It is especially important to track the movements of patients undergoing complex surgical interventions. The article aims to assess the applicability of optical technologies for determining the location of patients inside a hospital building.The article contains an analytical review of scientific sources devoted to local positioning based on optical technologies. The study revealed the advantages and disadvantages of the considered approaches. Each of them can be used in medical local positioning systems.Recommendations for selecting the technological basis of local positioning systems are presented, reflecting the features of use in medical institutions.
