Abstract
Objective. To study the accuracy of 3D surface reconstruction of human body model by computer optical topography as compared to a multislice computed tomography.
Material and Methods. A model of a trunk dorsal surface of a patient with III Grade right side scoliosis in the thoracic spine was used for study. Computer optical topography was performed with a serial installation TODP, METOS Ltd., and multislice computed tomography – with a helical tomograph Siemens Somatom Sensation 4.
Results. Comparison of obtained magnitudes of clinical parameters, which are the most significant for diagnostics of spine deformity, revealed that difference in their meanings did not exceed ±0.5 mm for metrical and ±0.5° for angular parameters.
Conclusion. Computer optical topography ensures the accuracy of 3D surface reconstruction of human body model, which is comparable to that of a multislice computed tomography, and provides noninvasive and reliable assessment of important clinical parameters of a human body dorsal surface.
