Which of the following techniques can minimize radiation exposure during fluoroscopy?

Collimating the x-ray beam is a critical technique for minimizing radiation exposure during fluoroscopy. Collimation involves narrowing the x-ray beam to the area of interest, which reduces the amount of tissue that is exposed to radiation. By limiting the exposed area, collimation not only reduces the overall radiation dose received by the patient but also enhances image quality by decreasing scatter radiation. This focused approach helps in maintaining the necessary diagnostic information while ensuring that unnecessary radiation is not directed to surrounding tissues.

In contrast, increasing the frame rate, utilizing lower kilovoltage peak (kVp), and increasing milliampere-seconds (mAs) may not effectively reduce radiation exposure. A higher frame rate can lead to more radiation being used without improving diagnostic quality, lower kVp may require higher mAs to maintain image quality, and increasing mAs directly increases radiation exposure. Thus, the practice of collimation stands out as an essential protective measure in radiation safety during fluoroscopy procedures.
