Moving x-ray grid
- Definition
- A component of a diagnostic x-ray system designed as a moving grid to automatically move back and forth in a linear or reciprocating fashion during an x-ray exposure or exposure sequence. It typically consists of lead (Pb) foil strips separated by x-ray transparent (radiolucent) spacers and is used to absorb scatter radiation, eliminate artefacts and improve image contrast. Depending on its design, it moves in 1 or 2 dimensions during an x-ray exposure. Exposures are coordinated at the point in time in which the grid stops to change direction. The motion is used to blur out the shadows cast by the lead strips, and eliminate grid lines from exposed diagnostic x-ray films.
