Leg Rotation
Internal rotation of the legs improves visualization of the femoral necks. Lack of rotation can hide fractures. Proper positioning enhances diagnostic clarity. Leg rotation is a key step.
Centering Accuracy
Centering at the midpoint between the ASIS landmarks ensures full coverage. Off centering can cut off essential anatomy. Proper centering improves exposure index accuracy. It also reduces repeat imaging.
Rotation Checks
Symmetry of iliac wings and obturator foramina helps detect rotation. Rotation can mimic pathology. Checking alignment prevents misinterpretation. Rotation control is essential.
Scatter Reduction
Tight collimation reduces scatter and improves contrast. Digital detectors benefit from reduced field size. Proper collimation enhances clarity. Scatter control is vital.
