Which features of fluoroscopic equipment help reduce radiation exposure to the patient?

The features that help reduce radiation exposure to patients in fluoroscopic equipment include collimation and the deadman switch.

Collimation is a critical component because it involves narrowing the x-ray beam to the area of interest. By limiting the size of the beam, collimation ensures that only the necessary area is irradiated, which minimizes unnecessary exposure to surrounding tissues. This targeted approach not only protects adjacent organs and tissues but also enhances image quality by reducing scatter radiation.

The deadman switch is a safety feature that requires continuous pressure from the operator to maintain the x-ray beam. This means that if the operator were to let go of the switch, the radiation exposure would cease. As a result, the deadman switch helps to prevent unintended exposure to the patient by ensuring that the x-ray beam is only active when specifically intended by the operator.

Together, these features significantly contribute to lowering radiation doses, thus promoting safer fluoroscopic procedures for patients.
