•Patient Position

• �ٍSupine with leg extended

• Part position• Adjust knee to cassette • Slightly rotate leg medially• to centralize patella• Central Ray• 5-7 degrees cephalic

• Center Point

• ½ inch inferior to patellar apex • Structure shown• Femorotibial joint • Distal femur and proximal • tibia & fibul
