What practice in digital imaging helps avoid the possibility of repeats by overexposing the patient?

The practice that helps avoid the possibility of repeats by overexposing the patient is exposure creep. In digital radiography, exposure creep refers to the tendency of radiographers to increase exposure levels beyond what is necessary for adequate image quality. This phenomenon occurs because digital imaging systems are designed to handle a wide range of exposure levels, allowing for a greater latitude in terms of radiation dose.

By being aware of exposure creep, radiographers can be mindful of the amount of radiation they are using and can adjust their techniques to ensure they are providing the appropriate dose to achieve the necessary image quality without unnecessarily overexposing the patient. This concept is critical in promoting patient safety while still obtaining high-quality diagnostic images.

The other practices mentioned do not directly address the issue of overexposure. Image enhancement deals with improving the quality of images after they have been captured. Image normalization refers to adjusting the image data to a consistent scale, which does not inherently prevent overexposure. Contrast adjustment is focused on changing the visibility of structures within the image rather than on managing exposure levels during the imaging process. Therefore, understanding and managing exposure creep is essential for optimizing radiation dose while maintaining high-quality imaging.
