- Focused Grid: A focused grid is designed to compensate for the divergence of X-rays as they pass through the patient’s body. It consists of lead strips that are angled toward a focal point, which corresponds to the X-ray source. The strips are closer together at the top and farther apart at the bottom.

The grid strips of a focused grid are angled so that they are aligned with the pattern of the x-ray beam. So if the x-ray tube is placed at a source-image distance corresponding to the grid focusing distance, this would be the best place to allow the primary photons to get through the grid.

Sep 21, 2022 · X-ray grids are devices used in radiography to improve the quality of images by reducing the amount of scattered radiation that reaches the X-ray detector or film. The basic purpose of X-ray grid use is to enhance the contrast and quality of the medial image by removing the scatter radiation.
Focused grids have lead strips that are oriented parallel at the center (along the x-ray central axis) and progressively slanted to the periphery to match the beam divergence from the focal spot .to the detector at a specific source to detector distance.
Apr 10, 2019 · A grid, fully named an “X-Ray Antiscatter Grid,” is comprised of alternating lines of lead and another, much more X-ray transparent material, that is put directly in front of the detector...

Focused grids can improve the quality of X-ray radiography for medical devices. The purpose of focused grids is to filter scattered lines, reduce gray haze and improve contrast. When the thickness and density of the object are relatively large, the quality of the photograph can be improved by using the filter grid.
Focused grids are placed between the human body and the film. Focused grids filters most of the scattered lines, but only a small fraction of them leak.
