AP IR Size: 14x17 Bucky CW SID: 40'' Page #'s: 1:337,134	Positioning:   • =Pt supine   • (If no suspected Fx) Separate heels 8''-10'' & medially rotate feet 15°-20°   • TOF 1''-1.5'' Superior to iliac crests	CR Entrance & Angle:   • _|_ 2'' inferior ASIS or 2'' superior pubic symphysis   • Collimation:   •	Eval Criteria:   • NR-Both ilia & Both greater trochanters equidistant to the edge   • Lower vertebral column centered   • NO SI of femoral necks   • Entire pelvis along with the proximal femora   • Must include iliac crests & proximal femur   • Femoral neck & greater trochanter in profile   • Symmetric obturator foramina, Ischial spines equally shown, Symmetric ilia alae, Sacrum & coccyx aligned with the pubic symphysis
AP Oblique (Modified Cleaves) IR Size: 14x17 Bucky CW SID: 40'' Page #'s: 1:342,126	Positioning:   • =Pt supine   • (If no suspected Fx) Flex knees as much as possible   • abduct thighs as much as possible (approx 45° from vertical)   • soles of feet against each other	CR Entrance & Angle:   • _|_ MSP 1'' superior pubic symphysis   • Collimation:   •	Eval Criteria:   • NR of pelvis, as evidenced by a symmetric appearance   • No SI of Femoral neck by the greater trochanter; excess abduction causes the greater trochanter to obstruct the neck.   • Lesser trochanter on the medial side of the femur   • Femoral axes extended from the hip bones at equal angles   • Acetabulum, femoral head, & femoral neck Shown
