Heterogeneous Consistency Loss for Cobb Angle Estimation

2021 43rd Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2021
Cobb angle is the most common quantification of the spine deformity called scoliosis. Recently, automatic Cobb angle estimation has become popular with either semantic segmentation networks or landmark detectors. However, such methods can not perform robustly when some vertebrae have ambiguous appearances in X-ray images. To alleviate the above problem,

Can C2-6 Cobb Angle Replace C2-7 Cobb Angle?

Spine, 2019
Study Design. Retrospective study of consecutive 113 cervical kinetic magnetic resonance images (kMRIs) and 57 radiographs. Objective. To elucidate the relationship between C2-6 or C2-7 Cobb angle and cervical sagittal alignment parameters using kMRI, and evaluate the visibility of ...

Variation in Cobb angle measurements in scoliosis

Skeletal Radiology, 1994
In order to determine the reliability of the Cobb angle measurement as it is used in the clinical management of scoliosis, a methodological survey was carried out. In the measurement of a Cobb angle two phases can be distinguished: (a) the production of a spinal radiograph and (b) the measurement of the angle itself.

Analysis of Cobb angle measurements in scoliosis

Clinical Biomechanics, 1987
The measurement of the magnitude of the deformity in idiopathic scoliosis is usually performed by either the Cobb method or the Ferguson method. In this study an error analysis of the Cobb method is given. The projection error is 3° and is more or less the same in moderate and severe scoliosis.

MPF-net: An effective framework for automated cobb angle estimation

Medical Image Analysis, 2022
In clinical practice, the Cobb angle is the gold standard for idiopathic scoliosis assessment, which can provide an important reference for clinicians to make surgical plan and give medical care to patients. Currently, the Cobb angle is measured manually on both anterior-posterior(AP) view X-rays and lateral(LAT) view X-rays.

3D modeling of musculoskeletal Cobb's angles

2013 6th International Conference on Biomedical Engineering and Informatics, 2013
The growth of industries has led to not only the improvement in quality of life but also increased musculoskeletal diseases due to accumulation of micro-sized damages in muscles or other tissues due to simple and repetitive lifestyle. Similarly, having curvature in the vertebrae is referred to as scoliosis, which is increasingly occurring mostly in ...

Validity of Cobb angle measurements using digitally photographed radiographs

The Spine Journal, 2011
Advances in technology are influencing the way that medical information is archived and shared. Considering that an estimated two-thirds of the world has little or no orthopedic care, high demand exists for adequate consultation regarding diagnostic images in orthopedic specialties.To validate the use of photographed scoliosis films for the accurate ...

Surface Topography, Cobb Angles, and Cosmetic Change in Scoliosis

Spine, 2001
Preliminary analysis of the clinical value of surface topography in a spinal deformity clinic.The Cobb angle is the gold standard for the monitoring of scoliosis. This study was designed to determine whether surface topography would reflect Cobb angle status with sufficient reliability to permit its safe use as an alternative means of documentation in ...

Computer-Assisted Cobb Angle Measurement on Posteroanterior Radiographs

2008
The Cobb angle method is the gold standard to assess severity of scoliosis. A computer-aided method was developed to provide a semi-automatic Cobb angle measurement during a scoliosis clinic. This study was to evaluate the reliability and accuracy of the developed method. Curve types were also tested.

Reexamination of the Cobb and Ferguson Angles

Journal of Spinal Disorders, 1993
In scoliosis, the Cobb measure of curve severity has been recommended over the Ferguson method because it had greater magnitude and appeared more sensitive to changes during progression and after treatment. This study made comparisons between the Cobb and Ferguson measures in radiographs of patients with idiopathic scoliosis to test whether the methods
