When a grid is used to reduce x-ray scatter it increases the contrast by a contrast improvement factor (k), but additional radiation dose is needed to compensate for the photons blocked by the grid (Bucky Factor).

In 1913, Dr. Gustave Bucky invented a device called the grid. The grid is placed between the patient and the image receptor. The grid absorbs scattered radiation and prevents the scatter from reaching and affecting the image receptor. When a grid is used, radiographic contrast increases.
The antiscatter grid plays an important role for enhancing image quality in projection radiography by transmitting a majority of primary radiation and selectively rejecting scattered radiation.
Feb 27, 2016 · Radiographic grids are used to improve radiographic image quality by absorbing scatter radiation that exits the patient, reducing the amount of scatter reaching the IR. It should be noted that grids do nothing to prevent scatter production; they merely reduce the amount of scatter reaching the IR.
Jan 1, 2023 · An anti-scatter grid is often used in X-ray radiography to reduce the scattered X-rays generated from the patient. However, the presence of a grid means the patient dose subsequently increases. Recently, several manufacturers have developed software that is capable of correcting for scattered X-rays without the use of a conventional grid. This ...
Jun 30, 2011 · The x-ray source generates a series of narrow beams using an electronically deflected focal spot. The beams are sequentially captured by a small stationary detector. Due to the narrow x-ray beams, scatter is significantly reduced.
Anti-scatter Grid: If scatter can not be reduced with other means anti-scatter grids can be used to preferentially stop scattered photons. BUCKY Factor: Anti-scatter grids are used to boost the contrast but there is an associated dose penalty expressed as the Bucky Factor. Download Now. Recommendations. I absolutely love this website!
