In mobile fluoroscopy equipment, what is the optimal source-to-skin distance?

In mobile fluoroscopy equipment, the optimal source-to-skin distance is crucial for minimizing radiation exposure to the patient. The recommended distance is typically around 30 cm, which provides a balance between effective imaging and safety. The closer the radiation source is to the patient’s skin, the higher the dose of radiation they receive, which is why regulations and safety standards aim to maintain a minimum distance to protect the patient.

A distance of 18 cm is less than the recommended standard and could lead to increased radiation exposure, which is not in alignment with best practices for patient safety. The goal is to maintain as much distance as is practical to reduce this exposure while still obtaining the necessary diagnostic images. Other distances, such as 45 cm or more, while effective in reducing dose, may not always be achievable with mobile units due to their design and the need for maneuverability in clinical settings. Thus, maintaining a source-to-skin distance of 30 cm is a well-established guideline in the use of mobile fluoroscopy.
