Automatic 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.

A framework for human spine imaging using a freehand 3D ultrasound system.

The use of 3D ultrasound imaging to follow the progression of scoliosis, i.e., a 3D deformation of the spine, is described.
