Vertebral shape: automatic measurement with active shape models.
The shape and appearance of the spine on lateral dual x-ray absorptiometry scans were statistically modeled. To measure vertebral shape accurately, rapidly, and automatically with a computer, this trained model was matched to findings on previously unseen scans. The technique obtained entire shape information, was faster than manual analysis, and was as accurate as human observers in the measurement of vertebral shape.
