Cobb Angle Measurement of Scoliosis with Reduced Variability
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...
متن کاملAutomatic Cobb angle determination from radiographic images.
STUDY DESIGN Automatic measurement of Cobb angle in patients with scoliosis. OBJECTIVE To test the accuracy of an automatic Cobb angle determination method from frontal radiographical images. SUMMARY OF BACKGROUND DATA Thirty-six frontal radiographical images of patients with scoliosis. METHODS A modified charged particle model is used to determine the curvature on radiographical spinal i...
متن کاملCobb Angle Measurement of Scoliosis Using Computer Measurement of Digitally Acquired Radiographs-Intraobserver and Interobserver Variability
STUDY DESIGN We evaluated computer assisted digital measurement of radiographic parameters in patients with idiopathic scoliosis. PURPOSE To assess the reliability of digital measurements. OVERVIEW OF LITERATURE Various authors analyzed scoliotic deformities by conventional radiographs, but very few studies have addressed the reliability of digital radiographic measurement using computer so...
متن کاملThe effect of patient positioning during radiographs on the resulting Cobb angle measurements
Background Standing spinal radiographs have been the primary method of spinal deformity evaluation in patients with scoliosis. During periods of patient surveillance, the clinician compares radiographs over a period of time to assess the progression of the deformity [1-3]. One of the potential problems in comparing one radiograph to another is difference in positioning [4-6]. The goal of this s...
متن کاملA Semi-Automatic Algorithm for Estimating Cobb Angle
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 ...
