ABSTRACT:
A stereofluoroscopy system has a source of radiation to radiate an object. The source may be one or two x-ray tubes. Conversion means receives radiation from the source and converts it into a composite video signal. The conversion means may include an image intensifier tube associated with a conventional television camera. The composite video signal is received by transmission means which may include switching apparatus and circuitry together with a video storage device to selectively receive even and odd fields for subsequent transmission to display means. The display means includes a television monitor to receive the video signal and a field synchronization detector to detect the video synchronization signal. Means are provided to transmit a synchronization signal to portable electro-optic shutter viewers to be positioned in front of the eyes of the viewer to obtain a three-dimensional stereoscopic view of the television monitor. Controller means are provided to supply control signals to the switching apparatus and circuitry in the transmission means. The controller means also provide control signals to position the source and conversion means as desired by the user. Cursor means may also be included to provide a three-dimensional cursor to be viewed by the user.
