What leads to the need for adjusting exposure factors when using a grid?

When using a grid in radiography, the primary purpose is to reduce the amount of scatter radiation that reaches the image receptor, thereby improving the quality of the image. Grids are designed to absorb scatter radiation while allowing primary radiation to pass through. However, because grids can reduce the overall amount of incoming radiation to the image receptor, it necessitates the adjustment of exposure factors for accurate imaging.

In situations where scatter radiation is effectively absorbed by the grid, less radiation reaches the image receptor. As a result, to compensate for this reduction, radiographers must increase the exposure factors such as the mA (milliamperes), the time (seconds), or the kVp (kilovolt peak). This adjustment is essential to ensure that the image is adequately exposed despite the grid’s presence, which inherently reduces the number of photons that hit the receptor.

The other options relate to various aspects of radiographic technique but do not specifically address the need for adjustment due to the utilization of a grid. Patient thickness could indeed influence exposure settings, but not specifically due to the grid. Image receptor sensitivity might allow for a lower dose overall, but this too does not directly correlate with the need to adjust due to the grid's role. Increased distance from the x-ray
