This has raised concern regarding the effects of this repeated exposure. Modern technologies for assessing spinal\u00a0deformities are based on assessment of the surface topography of the back in various ways. Photogrammetry can contribute in direct\u00a0measurement of the patient\u2019s back and 3D reconstruction of surface shape. This paper describes the instrumentation, technique and\u00a0the results of a portable system for screening for scoliosis. It is based on digital photogrammetric techniques and gives an accuracy of\u00a01mm in 3D reconstruction of the back. From this, spinal deformations indices are derived and clinically tested for correlation to the\u00a0Cobb angle radiographic measurements, which are considered the \u201cgolden standard\u201d in scoliosis assessment.<\/p>\n<table align=\"center\">\n<tbody align=\"center\">\n<tr align=\"center\">\n<td align=\"center\" width=\"50%\"><a href=\"http:\/\/www.mpateraki.org\/wp-content\/uploads\/2006\/10\/1214_Dresden06_1.bmp\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-365 size-medium\" src=\"http:\/\/www.mpateraki.org\/wp-content\/uploads\/2006\/10\/1214_Dresden06_1-249x300.bmp\" alt=\"\" width=\"249\" height=\"300\" srcset=\"https:\/\/mpateraki.org\/wp-content\/uploads\/2006\/10\/1214_Dresden06_1-249x300.bmp 249w, https:\/\/mpateraki.org\/wp-content\/uploads\/2006\/10\/1214_Dresden06_1.bmp 563w\" sizes=\"auto, (max-width: 249px) 100vw, 249px\" \/><\/a><\/td>\n<td align=\"center\" width=\"50%\"><a href=\"http:\/\/www.mpateraki.org\/wp-content\/uploads\/2006\/10\/1214_Dresden062_1.bmp\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-366 size-medium\" src=\"http:\/\/www.mpateraki.org\/wp-content\/uploads\/2006\/10\/1214_Dresden062_1-300x268.bmp\" alt=\"\" width=\"300\" height=\"268\" srcset=\"https:\/\/mpateraki.org\/wp-content\/uploads\/2006\/10\/1214_Dresden062_1-300x268.bmp 300w, https:\/\/mpateraki.org\/wp-content\/uploads\/2006\/10\/1214_Dresden062_1.bmp 751w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p>Patias P., Stylianidis E., Pateraki M., Chrysanthou Y., Contozis C., Zavitsanakis Th., 2006. 3D digital photogrammetric reconstructions for scoliosis screening.
