Which of the following is a method to reduce patient exposure during radiographic procedures?

Using high-speed film or digital sensors is indeed a method to significantly reduce patient exposure during radiographic procedures. High-speed film or digital sensors have increased sensitivity to radiation, which allows for the capture of diagnostic-quality images with lower doses of radiation. This technology minimizes the amount of exposure by requiring less time to obtain the necessary images while still ensuring adequate image quality for diagnostic purposes.

In contrast, increasing exposure time unnecessarily leads to higher doses of radiation exposure to the patient, which is counterproductive to radiation safety principles. Reducing the angle of the x-ray beam might not necessarily decrease exposure; it could potentially lead to the need for additional images or repeated exposures. Moving the x-ray source closer to the patient can increase the radiation dose received, as the intensity of radiation increases as the source approaches the target. Therefore, utilizing high-speed film or digital sensors is a proven strategy for enhancing patient safety by minimizing radiation exposure while providing the required imaging quality.
