FFD, or Focus-Film Distance, refers to the distance between the x-ray tube and the film or detector in radiology. This measurement is crucial for determining image quality, as it influences the sharpness and resolution of the radiographic image. A proper FFD helps ensure optimal exposure and minimizes distortion, ultimately aiding in accurate diagnoses. Adjusting FFD can also impact radiation dose to the patient, making it an important consideration in radiographic technique.
