Which practice is effective in reducing patient exposure during fluoroscopy?

Applying collimation to the clinical area is an effective practice in reducing patient exposure during fluoroscopy. Collimation involves narrowing the x-ray beam to the area of interest, which minimizes the volume of tissue irradiated and consequently reduces the amount of scatter radiation the patient is exposed to. This targeted approach not only protects surrounding tissues but also enhances image quality by reducing the amount of background noise that can obscure diagnostic information.

By limiting the exposure to just the necessary area, collimation plays a crucial role in optimizing radiation safety for the patient while still allowing for adequate visualization of the clinical area of interest. This practice is widely endorsed as part of the principles of radiation protection, emphasizing the importance of minimizing exposure whenever possible.
