Scoliosis evaluation utilising truncal cross-sections

摘要: In scoliosis, two basic structural changes, i.e. lateral flexion and axial rotation, result in the characteristic spinal deformity. Radiography has proved satisfactory measuring However, at present there is no method to measure rotational A latter deformity by drawing out cross-sections of trunk been developed: projection a horizontal laser beam on body surface detected an inclined line sensor camera. The camera are simultanelously moved around patient output data converted, minicomputer, into cross-section graphic display or x-y plotter. To evaluate quantitatively, we introduced indices proposed algorithms for their calculation. Measuring crosssections 59 scoliosis patients, analysed relationship between Cobb angle.
