Anisotropy Estimation of Trabecular Bone in Gray-Scale: Comparison Between Cone Beam and Micro Computed Tomography Data

Measurement of anisotropy of trabecular bone has clinical relevance in osteoporosis. In this study, anisotropy measurements of 15 trabecular bone biopsies from the radius estimated by different fabric tensors on images acquired through cone beam computed tomography (CBCT) and micro computed tomogRodrigo Moreno Department of Radiology and Department of Medical and Health Sciences Linköping University, Linköping, Sweden Center for Medical Image Science and Visualization (CMIV) Linköping University, Linköping, Sweden Linköping University, Campus US, 581 85 Linköping, Sweden, e-mail: [email protected] Magnus Borga Department of Biomedical Engineering Linköping University, Linköping, Sweden Center for Medical Image Science and Visualization (CMIV) Linköping University, Linköping, Sweden e-mail: [email protected] Eva Klintström Department of Radiology and Department of Medical and Health Sciences Linköping University, Linköping, Sweden Center for Medical Image Science and Visualization (CMIV) Linköping University, Linköping, Sweden e-mail: [email protected] Torkel Brismar Department of Radiology, Karolinska University Hospital at Huddinge, Huddinge, Sweden, e-mail: [email protected] Örjan Smedby Department of Radiology and Department of Medical and Health Sciences Linköping University, Linköping, Sweden Center for Medical Image Science and Visualization (CMIV) Linköping University, Linköping, Sweden e-mail: [email protected]
