Where is the grid typically placed in mammography?

In mammography, the grid is typically placed between the patient and the detector. This positioning is essential for reducing the amount of scatter radiation that reaches the detector, which can degrade image quality. When the grid is situated in this location, it effectively absorbs the scattered photons while allowing the primary x-ray beam to pass through.

The presence of the grid is crucial in mammography due to the high contrast required for the images, especially since breast tissue can produce a significant amount of scatter. By improving image quality and contrast, the grid helps radiologists to better identify potential abnormalities, such as tumors or microcalcifications. Therefore, the correct placement of the grid is vital for achieving the high standards of diagnostic quality expected in mammography.
