Understanding Grid Types in Imaging Technology
Explore different types of grids used in imaging technology such as Parallel, Crossed, Focused, and Moving Grid (Potter-Bucky). Learn about their advantages, disadvantages, and specific applications in radiography. The visual representations and detailed descriptions provide insights into how these grids function to improve image quality by reducing scatter radiation and enhancing diagnostic accuracy.

Types of Grid Parallel Crossed Focused Moving Grid (Potter Bucky)
Parallel lead strips are parallel to each other, in their longitudinal axis Easy to design Disadv grid cut off --- attenuation of primary radiation is greater at the edges & it can be partial or complete cut off
Crossed Lead strips that are parallel to both the long axis and short axis of the grid.
Focused Mainly to reduce grid cut off
