Bone mri using b0 inhomogeneity map and a subject magnetic susceptibility map |
| abstract |
The invention provides for a medical instrument ( 100, 500 ) comprising a magnetic resonance imaging system ( 102 ) for acquiring magnetic resonance data ( 142 ) from a subject ( 118 ) within an imaging zone ( 108 ). The magnetic resonance imaging system comprises: a main magnet ( 104 ) for generating a B0 magnetic field within the imaging zone; a memory ( 134, 136 ) containing machine executable instructions ( 160, 162, 164, 166 ) and pulse sequence commands ( 140 ); a processor ( 130 ) for controlling the medical instrument. Execution of the machine executable instructions causes the processor to: acquire ( 200 ) the magnetic resonance data by controlling the magnetic resonance imaging system with the pulse sequence commands; receive ( 202 ) a subject magnetic susceptibility map ( 144 ) of the subject; calculate ( 204 ) a B0 inhomogeneity map ( 146 ) from the magnetic resonance data; calculate ( 206 ) a subject B0 magnetic field perturbation ( 148 ) from the subject magnetic susceptibility map; calculate ( 208 ) a residual B0 magnetic field perturbation ( 150 ) by subtracting the subject B0 magnetic field perturbation from the B0 inhomogeneity map; and calculate ( 210 ) a bone map ( 152 ) from the residual B0 magnetic field perturbation. |
