Exemplary embodiments of apparatus, method and system for determining a position on or in a biological tissue can be provided. For example, using such exemplary embodiment, it is possible to control the focus of an optical imaging probe. In another exemplary embodiment, it is possible to implement a marking apparatus together with or into an optical imaging probe. According to one exemplary embodiment, it is possible (using one or more arrangements) to receive information associated with at least one image of at least one portion of the biological tissue obtained using an optical imaging technique. Further, it is possible to, based on the information, cause a visible change on or in at least location of the portion(s) using at least one electro-magnetic radiation.
