26
Supine Skyline Patella
- 18x24cm - tabletop - bring patient to edge of table - flex knee 30* - angle 15* from tibia - 40-48" SID - use the wall to see the patella, so patient doesn't have to stretch for a long time - place IR at mid thigh so the patella is in the middle of the cassette - tilt IR to be parallel with tube - marker up
27
AP Pelvis
- 35x43cm - no rotation of pelvis - 40" SID - must include symphysis - center 2" below ASIS - rotate legs internally but not if fractured or dislocated(move the heels apart and toes together) - suspended respiration - triangle shielding on follow up view - lead apron to cover chest
28
AP Oblique Pelvis (Frog Legs) - bilateral
