To minimize radiation exposure during fluoroscopic examinations, the technologist should:

Employing pulsed fluoroscopy with the lowest acceptable frame rate is the most effective strategy for minimizing radiation exposure during fluoroscopic examinations. Pulsed fluoroscopy significantly reduces the amount of continuous radiation emitted by the x-ray tube by switching the x-ray beam on and off at intervals rather than providing a constant beam. This method allows for adequate imaging while simultaneously decreasing the overall dose of radiation that both patients and technologists are exposed to. It is particularly beneficial in procedures where continuous imaging is not strictly necessary, thus making it a valuable tool for optimizing radiation safety.

In contrast, the use of the last image hold feature, while beneficial for some procedures, does not contribute to minimizing radiation exposure. Modifying the automatic exposure rate control settings can be tricky and may not always lead to lower radiation doses if not aligned with the specific needs of the examination. Increasing exposure factors generally leads to higher radiation doses, which contradicts the goal of reducing exposure. The focus should be on maintaining image quality while using techniques that naturally limit radiation output.
