X-RAY EXAMINATION APPARATUS |
摘要 |
In an X-ray image intensifier-television pickup tube apparatus for displaying an image with a small contrast difference, the beam current of the television camera tube can be temporarily increased. As a result, images can be displayed with an increased signal-to-noise ratio. The television camera can then be switched, preferably automatically between this form of image production and the usual production of fluoroscopic images. |
