To decrease the amount of scatter and improve image quality in radiographs, what adjustment can be made?

Decreasing the field size in radiographic imaging is effective in reducing scatter radiation, which directly contributes to improved image quality. When the field size is reduced, the area exposed to radiation is minimized, leading to a smaller volume of tissue being irradiated. This reduction in tissue not only decreases the overall amount of scattered photons generated but also restricts the area where scatter can interfere with the diagnostic image. As a result, the radiograph will display improved contrast and clarity, allowing for better visualization of the structures of interest.

In contrast, increasing field size would increase the amount of scatter, thereby reducing image quality. Decreasing the time of exposure has minimal direct impact on scatter, as scatter is more related to the volume of tissue being imaged rather than the duration of exposure. Furthermore, adjusting kilovoltage settings primarily affects penetration but doesn't have a direct effect on scatter in the same way field size does. Therefore, the strategy of decreasing field size is a well-established method to enhance the quality of radiographic images by managing scatter effectively.
