NHANES II Spinal X-ray with Extra Labels For Reference Vertebral Bodies (C2, S1)

The NHANES radiographs (https://www.nlm.nih.gov/databases/download/nhanes.html) were scanned by Dr. Bernie Huang at the University of California at Los Angeles and the University of California at San Francisco. It originally contained 17,000 Spinal X-rays with 600 of them annotated with vertebra coordinates. Based on this fact we invited two internal radiologists to create extra reference vertebra coordinates for S1 and C2 for these 600 annotated X-rays. The project is sponsored by Novartis and the University of Oxford jointly.
