STEREOFLUOROSCOPE WITH IMAGE INTENSIFIER

Abstract

Several types of stereofluoroscope have ever been devised, which are mostly composed of left and right roentgen tubes alternately excited, a fluorescent screen and a rotating shutter synchronised ot the tubes. However, none of them can easily produce an ideal stereoscopic image of internal organs of human body, for image produced on the screen is so dark that we cannot get an adequate stereoscopic sense. Therefore, instead of the usual fluorescent screen, we have adopted an image intensifier tube which can remarkably increase the image brightness, and attached to it, an optical system consisting of a reflex came a, a beam splitter, a rotary sector and a binocalar arranged in order.
