What is the minimum source-to-surface distance (SSD) for a stationary unit?

The minimum source-to-surface distance (SSD) for a stationary unit is established at 38 cm. This requirement is in place to ensure adequate radiation safety for both patients and healthcare professionals.

Maintaining a minimum SSD helps reduce the exposure of surrounding tissues to unnecessary radiation and limits the amount of scattered radiation that could be hazardous in the vicinity of the fluoroscopic procedure. Standards set by various regulatory bodies, including the American College of Radiology and the Radiologic Society of North America, emphasize the importance of adhering to this specific distance to minimize risks associated with radiation exposure during diagnostic and therapeutic procedures.

The other distances provided may not comply with regulatory standards for stationary fluoroscopic units, which generally require a minimum of 38 cm to help ensure that the delivery of radiation is controlled and that safety protocols are strictly followed.
