X-RAY IMAGING APPARATUS
An X-ray imaging apparatus has an image intensifier for converting an X-ray shadowgram of a patient into visible light. A primary lens group collimates the visible light and a secondary lens group forms the image carried by the visible light on a TV imaging device. The primary lens group is provided...

| description | An X-ray imaging apparatus has an image intensifier for converting an X-ray shadowgram of a patient into visible light. A primary lens group collimates the visible light and a secondary lens group forms the image carried by the visible light on a TV imaging device. The primary lens group is provided with a beam splitter for reflecting a part of the light output by the image intensifier toward the secondary lens group and transmitting the remainder thereof to a pick-up optical system for detecting the brightness of the image output by the image intensifier. The exposure of the patient to X-rays can be controlled on the basis of the detected brightness. |
