Fig. 1. (A) EOS imaging system (https://www.eos-imaging.com/professionals/materials). Perpendicularly placed, vertically moving, co-linked units of X-ray tubes producing very thin collimated X-ray beams collected by unique line detectors with Nobel Prize-winning technology resulted in simultaneously captured biplanar digital images of a patient in a standing, weight-bearing position. (B) A space on which the patient stands. The width and length were about 76.5 cm each. (C) A patient with severe sagittal deformity whose entire body could not be examined with an EOS system.
