What is the preferred source-to-skin distance for C-arms?

• A. 10 inches
• B. 15 inches
• C. 20 inches
• D. 25 inches

Answer: (B)

The preferred source-to-skin distance (SSD) for C-arms is generally 15 inches. This distance strikes a balance between minimizing radiation exposure to the patient while ensuring high-quality imaging results. At 15 inches, the radiation is less concentrated compared to shorter distances, which helps reduce potential harmful effects on the skin and underlying tissues. This distance is recommended because it follows established safety protocols designed to protect both patients and medical personnel from excessive radiation exposure during imaging procedures. Consequently, adhering to this standard helps ensure that diagnostic images are obtained with an acceptable level of detail and clarity, which is crucial for effective patient care. In the context of C-arm usage, maintaining this preferred SSD is important for both safety and imaging efficacy, making 15 inches the most appropriate choice for clinical practice.
