In fluoroscopy, what is the significance of collimation?

The significance of collimation in fluoroscopy primarily lies in its ability to reduce unnecessary exposure to surrounding tissues. Collimation involves restricting the beam of radiation to the area of interest, which is critical for minimizing exposure to adjacent tissues and organs. By using collimation, healthcare providers can target the radiation precisely where it is needed, thereby lowering the overall radiation dose experienced by the patient.

This is particularly important not only for safety but also for adhering to the principles of radiation protection, which emphasize keeping exposure as low as reasonably achievable (ALARA). Properly collimating the radiation beam enhances patient safety without compromising the diagnostic quality of the images, ensuring that only the necessary area is exposed to radiation.
