30 degrees cephalic for males and 35 degrees cephalic for females.
2. Identify the correct CR angle and location for posterior and anterior oblique SI joints.
No CR angle on the tube head. Body positioned in a 25-30 degree obliquity. CR directed 1 inch medial to the upside ASIS.
3. Identify the positions that would best demonstrate on open right SI joint.

6. Identify the anatomy of the lumbar spine, sacrum and coccyx.
