Primary-beam collimator for stereo radiographic x-ray diagnostic apparatus A primary-beam collimator for a stereo radiographic x-ray diagnostic installation has an x-ray tube with dual focal points (F1, F2) arranged at a distance from each other. Shutter leaves (1a, 1b, 2a, 2b, 3a, 3b, ...
Shutter calibrationand customization of user settings are easily performed through the software menu, accessible via the display.Technical Specifications Stationary X-ray equipment for radiography is up to 150 kV tube voltage. Rectangular Field INNOVA C20 43 x 43 cm at 1m SID (maximum) INNOVA C8...
Its main function is to control the X-ray beam output field of the X-ray tube to satisfy the X-ray imaging diagnosis and make the projection range. Minimize, avoid unnecessary doses, and absorb some scattered light to improve image clarity. ...

Collimation is a form of shielding that operates at the X-ray source. Collimation reduces the X-ray source aperture using a remotely controlled lead shield within the housing of the X-ray tube, resulting in reduced exposure to the patient and operator. Typical collimation functions include circula...
(19) made of a highly X-ray-radiation-absorbent material and having a collimator opening (20) is arranged on the X-ray tube (1); and the collimator disk (19) is opposite the outlet window (4) on the side thereof facing away from the target and is located below the surface of the ...
PURPOSE: A collimator for an X-ray is provided to control an irradiation range of an X-ray by independently driving a first X shutter panel, a second X shutter panel, a first Y shutter panel, and a second Y shutter panel. CONSTITUTION: An X-ray emitted from an X-ray tube passes an...
A collimator includes a pair of first plate members which define an X-ray passing aperture by a spacing between their opposed end faces, a second plate member which is movable in a
An x-ray collimator that may include a substrate containing a plurality of holes, each hole being frustoconical at one end and tubular at the other end for use in an x-ray imaging system, whereby the x-ray collimator may be aligned with a two-dimensional array of x-ray sources and a ...
