What is the term that describes the ability of a grid to enhance contrast?

The term that describes the ability of a grid to enhance contrast is known as the contrast improvement factor. This concept is crucial in radiography and imaging because grids are used to absorb scatter radiation, which can obscure the image and reduce the clarity. By improving the contrast, the contrast improvement factor directly relates to how effectively grids can distinguish between different densities in an image, leading to sharper and more defined details.

The contrast improvement factor quantifies the degree to which a grid can improve image quality by providing a numerical value that indicates how much more contrast the resulting image exhibits compared to an image captured without a grid. This makes it an essential term in the context of imaging techniques where clarity and detail are paramount.

In contrast, grid ratio pertains to the density of lead strips in the grid; grid radius refers to the curvature of the grid, which is not directly linked to contrast enhancement; and image magnification relates to the size of an image compared to the object size, which is not connected to contrast but rather to scale and detail representation.
