What is the standard SID (Source-to-Image Distance) for a chest X-ray? The standard SID for a chest X-ray is 72 inches to reduce magnification and distortion of the heart. Why is it important to have the patient hold their breath during a chest X-ray? Holding the breath at full inspiration expands the lungs, providing a clear and accurate image of the chest structures. 2 What is the function of the collimator in a chest X-ray?
