Which of the following statements about lead strips within the grid is true?

In radiographic grids, lead strips play a crucial role in improving image quality by reducing scatter radiation. The correct statement about lead strips is that they are oriented vertically and absorb some of the useful beam.

This orientation allows the grid to capture scattered photons, which are produced when the primary beam interacts with body structures. The vertical arrangement permits useful radiographic beams that are traveling straight to pass through the interspaces between the lead strips while absorbing some degree of the primary beam. This absorption helps maintain image contrast and clarity by preventing the scatter from fogging the image.

The other statements either misrepresent the orientation of the lead strips or incorrectly assert that they absorb none of the useful beam, which would defeat the purpose of the grid in enhancing image quality.
