Population-based Respiratory 4D Motion Atlas Construction and its Application for VR Simulations of Liver Punctures
Andre Mastmeyer, Matthias Wilms, Heinz Handels
Virtual reality (VR) training simulators of liver needle insertion in the hepatic area of breathing virtual patients currently need 4D data acquisitions as a prerequisite. Here, fi…
Interpatient Respiratory Motion Model Transfer for Virtual Reality Simulations of Liver Punctures
Andre Mastmeyer, Matthias Wilms, Heinz Handels
Current virtual reality (VR) training simulators of liver punctures often rely on static 3D patient data and use an unrealistic (sinusoidal) periodic animation of the respiratory m…
A New 3D Segmentation Technique for QCT Scans of the Lumbar Spine to Determine BMD and Vertebral Geometry
Andre Mastmeyer, Klaus Engelke, Christina Fuchs +1
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 onl…
A New 3D Segmentation Methodology for Lumbar Vertebral Bodies for the Measurement of BMD and Geometry
Andre Mastmeyer, Klaus Engelke, Willi Kalender
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 accura…
