This patent describes a diagnostic x-ray machine for producing a radiographic image of a body, the image received by an x-ray sensitive medium. It comprises an x-ray source for producing a beam of x-ray radiation along a major axis directed through the body and toward the x-ray sensitive medium; a grid means positioned relative to the x-ray source, within the beam of x-rays after they pass through the body but prior to their reaching the x-ray sensitive medium for rejecting the x-rays scattered by the body; a reciprocating means for moving the grid means along an axis perpendicular to the major axis between a first limit and a second limit; a modulator means for controlling the intensity of the x-ray beam from the x-ray source; and a signal means for synchronizing the modulator means with the motion of the grid means between the first and second limit so as to control x-ray intensity as a function of grid velocity.
