An integrative framework for 3D cobb angle measurement on CT images.
Measuring the Cobb angle on computed tomography (CT) images remains a challenging but requisite task for clinical diagnoses of scoliosis. Traditionally, clinical practitioners resort to manual demarcation, but this approach is inefficient and subjective. Most of the existing computerized algorithms are two-dimensional (2D) and incapable of multi-angle calibration. ⋯ The new integrative framework is able to measure the Cobb angles in three imaging planes simultaneously and is therefore clinically advantageous.
