ABSTRACT:
An X-ray device and method of improving the quality of an image formed by an X-ray device are provided. The X-ray device comprises a source emitting a beam of X-rays toward an object to be examined. A detector for receiving the X-rays that pass through the object is connected to an image processor. An X-ray collimator comprising a translatable element and at least one aperture for narrowing the beam of X-rays is arranged between the X-ray source and the examined object. A method of improving the quality of an image formed by the X-ray device comprises the steps of narrowing the X-ray beam using the aperture of the collimator, moving the aperture through the X-ray beam to expose the object to be examined to the narrowed X-ray beam, and forming an image of the examined object based upon the highest intensity value received for each pixel of the detector.
