Surface topography systems are used in radiation-free monitoring and screening of scoliosis. This study examines the correlations of anatomical landmarks and parameters between torsobarography in a supine position and conventional surface topography in a standing position in 40 subjects. Overall, moderate correlations were observed between the two approaches, with a maximum Pearson correlation coefficient |r| of 0.63. Nonetheless, surface differences persist, which may be linked to both measurement inaccuracies and the variation in gravitational load across postures. These findings indicate that torsobarography holds potential as a complementary or alternative tool for radiation-free scoliosis assessment.
