Which of the following is a method to control distortion in radiographic images?

Controlling distortion in radiographic images is crucial for obtaining high-quality diagnostic images. The correct method here involves controlling motion. When a patient or the imaging equipment moves during the exposure, it can lead to blurriness and inaccuracies in the image, contributing to distortion. By minimizing motion—through techniques such as ensuring proper patient positioning, using immobilization devices, and providing clear instructions to the patient—radiographers can significantly enhance the clarity and accuracy of the resulting images.

While other factors like exposure time, radiation dose, and angle may play roles in the overall quality of the imaging process, they do not specifically address distortion caused by movement. For instance, controlling exposure time is essential for managing image brightness and preventing overexposure or underexposure; however, it does not directly reduce distortion arising from motion. Similarly, adjusting radiation dose is important for patient safety and image quality but does not impact motion-induced distortion. Controlling angles can influence image projection and shape but, like the other options, it does not inherently prevent motion-related distortion. Thus, the primary method for addressing distortion is indeed by managing motion effectively.
