Abstract
The invention provides for a medical instrument () comprising a magnetic resonance imaging system () for acquiring magnetic resonance data () from a subject () within an imaging zone (). The magnetic resonance imaging system comprises: a main magnet () for generating a B0 magnetic field within the imaging zone; a memory () containing machine executable instructions () and pulse sequence commands (); a processor () for controlling the medical instrument. Execution of the machine executable instructions causes the processor to: acquire () the magnetic resonance data by controlling the magnetic resonance imaging system with the pulse sequence commands; receive () a subject magnetic susceptibility map () of the subject; calculate () a B0 inhomogeneity map () from the magnetic resonance data; calculate () a subject B0 magnetic field perturbation () from the subject magnetic susceptibility map; calculate () a residual B0 magnetic field perturbation () by subtracting the subject B0 magnetic field perturbation from the B0 inhomogeneity map; and calculate () a bone map () from the residual B0 magnetic field perturbation.
