Which feature can be adjusted to improve image quality when a grid is not properly aligned?

When a grid is not properly aligned, positioning it correctly is essential for improving image quality. Grids are devices used in radiography to reduce scatter radiation and enhance the contrast of the resultant images. If a grid is misaligned, it can lead to artifacts, diminished image quality, or increased exposure required to achieve a diagnostic image.

Correctly positioning the grid ensures that the incoming X-rays are properly filtered, allowing for clearer images. By aligning the grid with the X-ray beam and the anatomical area of interest, it prevents uneven exposure and ensures that only the primary beam is effectively used, which in turn enhances the overall clarity and detail of the radiographic image.

While other choices mention altering exposure variables such as milliamperage, kilovoltage peak, or exposure time, these adjustments do not address the root problem of grid misalignment. Increasing exposure parameters may simply amplify the issues caused by a misaligned grid rather than rectify it. Thus, repositioning the grid correctly is the most effective means of improving image quality under these circumstances.
