What technique can assist in minimizing radiation exposure to patients?

Using the lowest possible dose of radiation is essential in minimizing radiation exposure to patients while still achieving sufficient image quality for diagnostic purposes. This principle aligns with the ALARA (As Low As Reasonably Achievable) concept, which emphasizes keeping radiation exposure to a minimum.

By optimizing the dose, healthcare providers can ensure that patients receive just enough radiation for effective imaging without exceeding the necessary amount, thereby reducing the risk of potential harmful effects associated with higher doses. This technique involves careful calibration of equipment and consideration of factors such as patient size, the area being imaged, and the specific requirements of the exam.

In contrast, extending the duration of exposure or conducting more frequent imaging sessions would increase the total radiation dose received by the patient, which contradicts the goal of minimizing exposure. Using larger film sizes can improve image quality and potentially reduce the need for repeat images, but it does not directly entail reducing radiation dose. Therefore, opting for the lowest possible radiation dose is the most effective and ethically responsible method for minimizing patient exposure.
