thanks alot mark I have the lights enabled and I see where to manipulate the ring scanner put when I animate it nothing happens I remember seeing a really good video (I think it was Spanish) where the scanner goes across the patient and this wicked blue light spits out of the ring.  Any idea how to achieve this effect? Also when I render my ssene the outlines of the lights can be seen in the render how do I get around that, any help is greatly appreciated Thanks!
