What is the minimum source-to-table distance required for fixed/stationary fluoroscopy?

The minimum source-to-table distance required for fixed or stationary fluoroscopy is indeed 38 cm. This specification is established to reduce the radiation exposure to both the patient and the healthcare providers during fluoroscopic procedures. By maintaining a minimum distance between the x-ray source and the table where the patient lies, the intensity of radiation that reaches the patient and operators is significantly minimized. This is crucial in medical environments where repeated exposures may occur, as it helps to adhere to the principle of keeping radiation doses as low as reasonably achievable (ALARA).

Understanding this minimum distance is vital for radiologic technologists and medical personnel involved in fluoroscopy since it directly impacts safety protocols and radiation protection strategies in clinical settings. Each of the other options suggests distances lower than the established requirement, which would not adequately protect patients and staff from potentially higher radiation doses.
