ABSTRACT:
An X-ray stereoscopic cinematography apparatus including an X-ray tube having at least a pair of focal spots from which X-rays are irradiated independently at an object to produce an X-ray image of an object under study, means for converting the X-ray image to an optical image, an optical system device for distributing the optical image to first and second cinecameras. The optical system device includes a first half-mirror having a reflection rate of approximately fifty percent and a second half-mirror having a comparatively low transmission rate, the half-mirrors being separately positionable in a first position to reflect the optical image or a second position out of the light path of the optical image to distribute the optical image to the first and second cinecameras. A television camera is provided to accept the optical image delivered through the optical system device and to convert it to an electric signal. A mode setter enables the selection of one of a stereoscopic cinematography mode, a single cinematography mode, and a fluoroscopy mode.
