Background: Scoliosis is the most common type of spinal deformity. A universal and standard method for evaluating scoliosis is Cobb angle measurement, but several studies have shown that there is intra- and inter- observer variation in measuring cobb angle manually.Objective: Develop a computer- assisted system to decrease operator-dependent errors in Cobb angle measurement.Methods: The spinal ...

Measurement of Cobb angle is the standard technique used for scoliosis assessment. The challenging task in computerized method lies in totally automating the method of curvature measurement from digital X-ray images. In this paper we presented a method which automatically measures the Cobb angle from radiographs after selection of the end vertebrae of the curve. The image processing methods use...

abstract introduction: this study was aimed at assessing the effect of a new thoracolumbar orthosis on patients with scheuermann's kyphosis referred to iran medical university of tehran in collaboration with a clinic of technical ortopedea in isfahan. material and method: this new version of orthosis had a dynamic system as compared to previous ones which enabled the spine to extend. a question...

BACKGROUND Supine imaging modalities provide valuable 3D information on scoliotic anatomy, but the altered spine geometry between the supine and standing positions affects the Cobb angle measurement. Previous studies report a mean 7°-10° Cobb angle increase from supine to standing, but none have reported the effect of endplate pre-selection or whether other parameters affect this Cobb angle dif...

BACKGROUND Although many studies on reliability and reproducibility of measurement have been performed on coronal Cobb angle, few results about reliability and reproducibility are reported on sagittal alignment measurement including the pelvis. We usually use SurgimapSpine software to measure the Cobb angle in our studies; however, there are no reports till date on its reliability and reproduci...

Background Brace treatment for scoliosis is effective. The short term in-brace correction of the Cobb angle is associated with end results and success of bracing. Irrespective of the factors which determine the correction the measurement of the Cobb angle is a possibility to evaluate the brace quality. We have investigated the braces from one orthotist over a fixed period of time and have descr...

Cobb angle, which is a measure of spinal curvature, is the standard method for quantifying the magnitude of Scoliosis, related to spinal deformity in orthopedics. Determining the Cobb angle through manual process is subject to human errors. In this work, we propose a methodology to measure the magnitude of Cobb angle, which appreciably reduces the variability related to its measurement, compare...

STUDY DESIGN Retrospective review of radiographic data. OBJECTIVES This study sought to define interobserver and intraobserver variability to further delineate reliable means by which radiographs of patients with neuromuscular scoliosis can be examined. SUMMARY OF BACKGROUND DATA Previous studies analyzed the use of Cobb angles in the measurement of idiopathic and congenital scoliosis, but ...

Objective To develop a computer-aided method that reduces the variability of Cobb angle measurement for scoliosis assessment. Methods A deep neural network (DNN) was trained with vertebral patches extracted from spinal model radiographs. The Cobb angle of the spinal curve was calculated automatically from the vertebral slopes predicted by the DNN. Sixty-five in vivo radiographs and 40 model r...
