A New 3D Segmentation Methodology for Lumbar Vertebral Bodies for the Measurement of BMD and Geometry

Autor: Mastmeyer, Andre, Engelke, Klaus, Kalender, Willi

In this paper a new technique is presented that extracts the geometry of lumbar vertebral bodies from spiral CT scans. Our new multi-step segmentation approach yields highly accurate and precise measurement of the bone mineral density (BMD) in differ

A New 3D Segmentation Technique for QCT Scans of the Lumbar Spine to Determine BMD and Vertebral Geometry

Autor: Mastmeyer, Andre, Engelke, Klaus, Fuchs, Christina, Kalender, Willi

Quantitative computed tomography (QCT) is a standard method to determine bone mineral density (BMD) in the spine. Traditionally single 8 - 10 mm thick slices have been analyzed only. Current spiral CT scanners provide true 3D acquisition schemes allo

A New 3D Method to Segment the Lumbar Vertebral Bodies and to Determine Bone Mineral Density and Geometry

Autor: Mastmeyer, Andre, Engelke, Klaus, Meller, Sebastian, Kalender, Willi

In this paper we present a new 3D segmentation approach for the vertebrae of the lower thoracic and the lumbar spine in spiral computed tomography datasets. We implemented a multi-step procedure. Its main components are deformable models, volume grow
