What is the minimum source-to-skin distance (SSD) for stationary fluoroscopic units?

The minimum source-to-skin distance (SSD) for stationary fluoroscopic units is set to ensure patient safety by reducing exposure to the skin while also maintaining image quality. A minimum SSD of 38 cm is established based on recommendations and standards to minimize the risk of skin injury from radiation. This distance helps in decreasing the amount of radiation delivered to the skin, thus enhancing safety during fluoroscopic examinations or procedures.

While other distances may be mentioned in various contexts, 38 cm is specifically recognized by guidelines as the required minimum for stationary units, making it significant for practitioners to adhere to this standard. This distance fosters a balance between effective imaging and protecting the patient from unnecessary radiation exposure.
