Abstract

When the acquisition of images is performed on human body structures, the safety of the person on which the images are being obtained acquires fundamental importance. This condition gathers even more relevance when the goal of the image acquisition is related with health examination. To ensure that every physician, when imaging human structures is undoubtedly secure that it will not harm or cause any non-tolerable discomfort to the subject undergoing the exam, medical devices have to surpass a set of specific norms depending on the nature of the structure being examined. More specifically related with instruments for eye related diseases diagnostic and treatment, the ISO-15004-2 norm is the currently accepted. As some types of eye exams rely on highly concentrated radiation, its power has to be limited in order to prevent irreversible damage. In this paper, a Light Hazard Measurement for a specific prototype will be addressed, on which the power calculation method for the emitted radiation will be described and the compliance of the limiting norms will be verified. The main conclusion from the work here described is that the prototype can be classified as a Group 1 Ophthalmic Device according to the ISO-15004-2 norm.
