[Oradlist] Fwd: White line on Digital Panoramic image

[Ricardo Urzúa]

Dr. Mapanda. I agree with Alan Farman. Here I am sending an image  that is
moreless the same you send, it appeared twice a few years ago,  In that time
a took a picture of the plastic head support. One of them was in a bad
position.
