摘要： An aperture device defines X-ray beams emitted from X-ray focal points L and R spaced apart from each other along the first direction. This defining operation is performed along the first direction and a second direction crossing the first position, thereby shaping a rectangular X-ray radiation area. Blades defining the two edges of the X-ray beam along the first direction and blades defining two edges of the X-ray beam along the second direction are supported by engaging portions into which screw portions of screw rods are screwed and engaging portions slidably fitted around round portions of the screw rods, respectively. When the screw rods are rotated by activation of corresponding stepping motors, the corresponding engaging portions are moved parallel to the screw rods. The respective blades can be variably moved along the first or second direction, thereby forming an X-ray radiation area having any shape in any position.

摘要： A stereoscopic projecting apparatus has a polyhedral prism and two types of polarizing filters which are arranged at the incident (or emerging) planes of the prism and which have orthogonal deflecting directions. Left and right-eye pictures are alternately formed on the consecutive frames of a cinefilm. The cinefilm is driven in such a way as to cross the projection region of light emitted from a lamp. An optical image transmitted from the cinefilm is projected onto a screen by the polyhedral prism, through a relay lens, a projection lens or the like. The left and right-eye images are deflected in directions 90.degree. apart from each other, by the polarizing filters at the respective incident or emerging planes of the prism. A viewer can stereoscopically observe the image superimposed on the screen, using polarized viewing glasses having polarized lenses deflected in the deflecting directions of the images.

摘要： An X-ray photographing apparatus includes first and second systems for photographing an object from different directions. A first arm of the first system supports a first X-ray tube thereon and is arranged to be rotatable. A second arm of the second system supports a second X-ray tube thereon and is arranged to be rotatable. When at least one of the arms is rotated, interference between the arms is prevented by an interference preventing device. The device has a storing section storing data relating to relative positions between the arms when at least one of the arms is rotated while an iso-center, i.e., the crossing point of X-ray beams emitted from the X-ray tubes coincides with the rotational centers of the arms. When at least one of the arms is rotated while the iso-center shifts from the rotational centers for a distance, a detecting section of the device detects the distance, and an operation section calculates, on the basis of the data and the detected distance, a position where the arms interfere with each other and controls the rotation of the arms according to the calculated interference position. When the arms come near the calculated interference position, the operation section actuates an alarm.

摘要： An X-ray fluoroscopic imaging apparatus capable of taking the fluoroscopic images of an arbitrary portion of an object to be examined from all directions without moving the object to be examined itself. The apparatus includes an arm member for supporting a fluoroscopic imaging device to be slidable along a circle centered around an isocenter; a supporting member for supporting the arm member to be rotatable in a vertical plane; and a carrier member for moving the support member in a horizontal plane, and for rotating the supporting member in the horizontal plane around a pivotal center not identical to the isocenter; where the carrier member, the supporting member, and the arm member are controlled such that the fluoroscopic imaging device can effectively be moved among positions distributed spherically around the isocenter, without changing an orientation of the supporting member with respect to the isocenter. The apparatus can also be effective in taking the fluoroscopic images of a region of interest in the object to be examined which requires more than one fluoroscopic imaging operations, without moving the object to be examined itself.
