Centering Accuracy
Centering at the iliac crest ensures full coverage of abdominal structures. Off centering can cut off essential anatomy. Proper centering improves exposure index accuracy. It also reduces repeat imaging.
Rotation Control
Symmetry of iliac wings and spinous processes helps detect rotation. Rotation can mimic organ enlargement or displacement. Checking landmarks prevents misinterpretation. Rotation control is essential.
Breathing Technique
Exposure on expiration reduces diaphragm movement. Proper timing improves organ visibility. Clear instructions enhance patient cooperation. Breathing control improves image quality.
Scatter Reduction
Tight collimation reduces scatter and improves contrast. Digital detectors are sensitive to unnecessary radiation. Proper collimation enhances diagnostic clarity. Scatter control is vital.
