A hierarchical 3D segmentation method and the definition of vertebral body coordinate systems for QCT of the lumbar spine

Abstract

We have developed a new hierarchical 3D technique to segment the vertebral bodies in order to measure bone mineral density (BMD) with high trueness and precision in volumetric CT datasets. The hierarchical approach starts with a coarse separation of the individual vertebrae, applies a variety of techniques to segment the vertebral bodies with increasing… (More)
