What condition leads to an increase in the production of scatter radiation?

The increase in the production of scatter radiation is closely associated with the use of a larger collimated field size. When the collimated field size is enlarged, a greater volume of tissue is irradiated. This results in more interactions between the x-ray photons and the matter in the body, as there’s a higher likelihood that photons will scatter as they pass through a larger amount of tissue. Scatter radiation occurs when x-ray photons are deflected from their original path after interacting with matter, which is more prevalent when the area being irradiated is expansive.

In contrast, using a smaller collimated field size limits the amount of tissue exposed to the x-rays, thereby minimizing scatter radiation. Similarly, adjusting the kVp (kilovolt peak) affects the energy and penetration power of the x-rays, with lower kVp potentially increasing scatter but not primarily due to the size of the irradiated field. Tissue compression can help reduce scatter by decreasing the amount of tissues that the x-ray beam passes through but does not directly correlate with the field size. Thus, the reasoning behind the answer focuses on the relationship between collimation size and the volume of tissue exposed, leading to increased scatter radiation.
