Magnification Control
Increasing SID reduces magnification and improves spatial resolution. Incorrect SID affects anatomical accuracy. Distance control enhances diagnostic value. Proper SID selection is essential.
Exposure Adjustment
Changing SID requires technique adjustments to maintain proper exposure. Monitoring exposure index ensures accurate detector response. Technique awareness improves consistency. SID control supports high quality imaging.
Distortion Reduction
Proper SID reduces geometric distortion. Incorrect distance can mimic pathology. Maintaining consistent SID improves reliability. Distance awareness enhances workflow.
Patient Positioning
SID changes affect patient positioning requirements. Proper alignment ensures accurate imaging. Awareness of distance effects improves technique. Positioning control is essential.
