A new computational approach for scoliosis assessment from a non-invasive body scanner

Abstract Idiopathic scoliosis is a three-dimensional deformity of the vertebral column and one common pediatric spinal diseases, while neuromuscular often associated with cerebral palsy. Especially during periods growth, there high risk progression scoliosis. Thus, frequent clinical monitoring important for proper treatment. X-rays are Gold standard most commonly used method follow-up The curvatures measured by Cobb angles from x-rays. Patients therefore accumulate higher ionizing radiation doses repetitive x-rays over their life span. Hence, reducing exposure to an consideration in adolescent For that purpose body scanner system proposed, particular, complementary diagnostics children adolescents non-invasive, free provides scan images human torso. In this study, two intermediate steps described useful development analysis methods images. Two-dimensional transverse cross sections torso can be extracted image along vertical axis. Here, will shape two-dimensional contours. Based on mathematical calculations polar coordinates, asymmetry between left right side captured linear fitting course contour either side. Further, data fitted ellipse.
