Coil correction of magnetic resonance images for trabecular bone analysis

Jenny Folkesson, Roland Krug, Ahi S. Issever, Sharmila Majumdar

Analysis of the trabecular bone is important in clinical studies related to fracture risk assessment and bone diseases such as osteoporosis, and magnetic resonance imaging (MRI) allows for noninvasive 3-D assessment of the bone. For studies of humans in vivo, bone MRI is typically acquired with phased array coils, which introduces intensity inhomogeneities into the scans than in turn influence the analysis of the trabecular bone.

Coil correction aims to automatically estimate and remove coil-induced bias fields from MRI data for more accurate and reproducible trabecular bone assessment.
