The determination is made after light has been reflected from the region after being supplied to the region from a light source by at least one optical fiber. The determination is made based on an analysis of the light reflected from the region and of a received at least one indication of a force applied to the material in the region by one or more of the at least one optical fiber. The indication of the force applied by the one or more of the at least one optical fiber is provided by at least one force sensor coupled to the at least one optical fiber.
