  2. Toes • Basic Projections • AP • Oblique AP Toes Exposure Factors • Patient position • Supine or seated on table • Knees flexed with feet separate

  3. Part position • Center toes with plantar surface flat Against cassette • Central Ray 15 degrees towards heal • Center Point • 3rd metatarsophalangeal joint • Structure shown • Metatarsals & phalanges

  4. Patient position Supine or seated on table Knees flexed with feet separated Part position Center toes with plantar surface flat Against cassette Medially rotate leg&foot30-45 degrees Central Ray Perpendicular Center Point 2 nd metatarcophalangeal joint Structure shown metatarsals & phalangesOblique view of • Oblique Toes

  5. Calcaneus • Basic Projections Lateral Axial Lateral Calcaneus Exposure Factors Patient Position lying upon affected side Adjust leg & foot in lateral position Part position Adjust patella perpendicular to table Adjust plantar surface perpendicular Center Calcaneus to cassette
