I went to visit Capt. Norberto Tapia last night at the Makati Medical Center and saw this weird looking contraption at the elevator. The unfriendly staff of MMC told me that it's an Image Intensifier.
"X-Ray Image Intensifiers are converting and amplifying a minimum amount of X-ray quanta into visible light providing high detail and high contrast images. Shortly after X-ray image intensifiers were invented, Siemens started to develop their own intensifiers."
