LASER POSITIONER FOR X-RAY EMITTER Russian patent published in 2009 - IPC H05G1/00 

FIELD: physics.

SUBSTANCE: invention can be used for aligning an X-ray emitter with respect to an object. The laser positioner for an X-ray emitter has a housing in which there is a laser with double-sided radiation output, two reflectors, the first of which is mounted at the intersection of the optical axis of the laser with the axis of the X-ray beam, and the second is mounted on the optical axis of the radiation output of the laser beyond the projection of the output window of the X-ray emitter on it, apparatus for indicating distance from the X-ray emitter to the object, two cylindrical lenses, mounted on the axis of the laser radiation across each of its output beams, the first cylindrical lens is mounted with possibility of moving in an out of the laser beam, a beam splitter, lying on the axis of the laser between the first reflector and the first cylindrical lens, a television camera, a spherical lens, mounted on the axis of the laser with possibility of moving it away from the laser beam and moving it into the position of the first cylindrical lens, a monitor. The laser positioner also has a diaphragm made from material which is not transparent to X-rays, mounted with possibility of its movement in and out of the X-ray beam on the axis of this beam and a holder with an X-ray luminescent plate of the same size as the film, used in radiographic test, in which on the axis, passing through the centre of the plate perpendicular to it, there is mirror mounted at an angle of 45° to that axis and an additional television camera, mounted on an axis, passing through the centre of the mirror, placed in the holder, the additional television camera has a cable and/or radio communication channel with an additional monitor.

EFFECT: provision for monitoring zones exposed to X-rays on the object side, opposite the X-rays, as well as easier determination of the distance from the focus of the X-ray tube to the film on the holder.
