Which of the following factors does NOT typically help in minimizing patient radiation exposure during fluoroscopy?

Utilizing higher exposure times does not help in minimizing patient radiation exposure during fluoroscopy; instead, it increases the amount of radiation the patient receives. In fluoroscopy, longer exposure times mean that the X-ray machine is active for an extended period, thereby delivering more radiation to the patient.

In contrast, increasing the source-skin distance effectively reduces radiation exposure because it decreases the intensity of the radiation reaching the patient. Adequate filtration also plays a crucial role in minimizing exposure; it removes low-energy X-rays from the beam that contribute little to useful imaging but significantly to patient dose. Additionally, minimizing the tabletop intensity reduces the amount of radiation emitted from the fluoroscopy machine, which directly lowers the patient’s exposure. Each of these strategies aims to optimize the balance between image quality and patient safety, highlighting that shorter exposure times are favored to minimize radiation dose.
