Xxray radiographic apparatus

Abstract: PURPOSE:To make possible photograhing by a cine camera of X-rays and sisplaying by a TV monitor as well by opposing a spot camera or optical system housing to the image plane of an image intensifier (II) which outputs X-ray visible images by a slide mechanism CONSTITUTION:A spot camera 2 or the optical system housing 6 provided with an objective lens 4, light quantity distributing mirror 5, TV camera 8, cine camera 7, etc is moved along stanchions 3 by a slide mechanism so that it opposes to the image exit plane of III formed with optical fibers Hence, it is possible not only to indirectly pick up the III which has been made to visible image through image conversion with a high-resolution X-ray image spot camera 2 but also to display the same in the TV monitor and continuously pick up the same with the cine camera 7, thus the diagnosis routines, etc of hospitals may be performed readily, rapidly and accurately

Binocular night glass

Abstract: An improved binocular night glass suitable for use with infrared light and relatively low levels of visible light without changing the viewing system, in particular its prism system. According to the invention the improvement comprises that the image converter includes two image conversion tube sections, only one of which results in image reversal.

Image conversion tube unit

Abstract: PURPOSE:To correct the pattern distortion for an output image and thus to obtain a good output image by providing a constant space at the attachment place of a magnetic field generator.
