How is radiation exposure minimized during radiographic procedures?

The correct approach to minimizing radiation exposure during radiographic procedures is through the use of the lowest effective radiation dose possible. This principle is central to the practice of radiography, as it aims to achieve the necessary quality of images for accurate diagnosis while ensuring patient safety.

Utilizing the lowest effective radiation dose involves adjusting several factors, such as the milliampere-seconds (mAs), kilovolt peak (kVp), and exposure time, to achieve optimal image quality without unnecessary exposure. Techniques such as optimizing imaging protocols, utilizing advanced imaging technologies, and adhering to the ALARA (As Low As Reasonably Achievable) principle are key components of this approach.

While other methods, such as patient cooperation to hold their breath or limiting the number of images taken, may contribute to reducing exposure, they do not address the fundamental goal of using the least amount of radiation necessary for quality imaging. Using the highest mA may lead to increased exposure without justification, which contradicts the principles of radiation safety.
