The Quantec Spinal Imaging System (QSIS) is a raster stereography used to measure three-dimensional trunk images. The Q angle, a coronal plane measurement generated by the Quantec Spinal Imaging System (QSIS), was compared with the Cobb angle in assessment of scoliosis curve magnitude. One hundred forty-nine patients with idiopathic scoliosis were evaluated using both the Quantec system and plane radiographs. The Cobb and Q angles demonstrated significant correlation in the thoracic region (r = 0.65, p < 0.05), lumbar region (r = 0.63, p < 0.05), and in the thoracolumbar region (r = 0.70, p < 0.05). The difference between the Q and Cobb angles was small when the Cobb angle was <21 degrees with less than 6 degrees of axial surface rotation, as measured by the QSIS method. For smaller curves with minimal rotation, there is close correlation between the Cobb angle and the Quantec angle.

A study of the contour of the surface of the back was conducted using the Quantec spinal image system (QSIS; raster stereophotography) and the Vicon 3-dimensional (3-D) motion analysis system with a plaster model of the scoliotic spine. With postural changes in 3 dimensions came alterations in the surface shape of the back. Most changes in QSIS parameters occurred in the coronal plane. The study showed that model 1, with 9 degrees of Q angle (similar to Cobb angle in the coronal plane) in right thoracolumbar scoliosis, altered 3-D metrics less than model 2 did, with 54 degrees of Q angle in scoliosis. The change in the position of the trunk in the transverse plane had a more significant impact on the QSIS parameters. Raster stereophotography has been used clinically to monitor curve progression. Changes in transverse rotation of the trunk correlate significantly with variations in Q angle and axial rotation. Clinicians using a raster stereophotograph system to assess scoliotic deformity need to control postural sway, as doing so results in more stable and reproducible measurements that can be used for clinical follow-up.
