What is the optimum source-to-skin distance for stationary fluoroscopic equipment?

The optimum source-to-skin distance (SSD) for stationary fluoroscopic equipment is 45 cm. This distance is important for minimizing the radiation exposure to the patient while still ensuring that high-quality imaging can be achieved. The farther the x-ray source is from the patient's skin, the lower the intensity of radiation that reaches the patient, effectively reducing the risk of potential harm.

Maintaining an SSD of 45 cm allows for a balance between image quality and patient safety. At this distance, the radiation dose is significantly less than it would be at smaller distances, and the risk of skin reactions or other side effects is minimized. This standard is supported by guidelines set forth by various health organizations, which advocate for protective measures in radiological practices.

In contrast, shorter distances such as 30 cm, 18 cm, or 12 cm would lead to higher radiation exposure and increased risk to the patient, making them less desirable from a safety perspective. The recommendation of maintaining a minimum of 45 cm aligns with practices that aim to optimize patient care and safety during fluoroscopic procedures.
