The skeleton of the pelvis:
2–4. Hip bone (os coxae)
1. Sacrum (os sacrum), 2. Ilium (os ilium), 3. Ischium (os ischii)
4. Pubic bone (os pubis) (4a. corpus, 4b. ramus superior, 4c. ramus inferior, 4d. tuberculum pubicum)
5. Pubic symphysis, 6. Acetabulum (of the hip joint), 7. Foramen obturatum, 8. Coccyx/tailbone (os coccygis)

The pelvic bones strictly consist of the sacrum, the coccyx and the hip bones (imaged). In radiology, the exam also includes the the proximal femurs (and the inferior vertebral column) because these also fall within the projections.
