What is the minimum distance required between the x-ray source and the x-ray tabletop for fluoroscopic equipment?

The minimum distance required between the x-ray source and the x-ray tabletop for fluoroscopic equipment is 15 inches. This distance is essential for radiation safety, as it helps to reduce the patient's exposure to radiation while still allowing for adequate imaging. The 15-inch distance is established based on regulatory standards and safety guidelines to ensure that the intensity of the radiation reaching the patient is minimized while still achieving clear diagnostic images. This practice supports the principle of ALARA (As Low As Reasonably Achievable), which aims to reduce radiation exposure to patients and staff. Ensuring adherence to this minimum distance is crucial for maintaining safe fluoroscopic practices in medical settings.
