MAGNETIC RESONANCE IMAGING APPARATUS AND CONTROL METHOD THEREOF |
| 摘要 |
A magnetic resonance imaging apparatus includes a magnetic assembly including a main magnet and a gradient coil unit and forming a static magnetic field and a gradient magnetic field in the bore thereof, and a gradient controller applying a test gradient waveform to the magnetic assembly, and compensating for a distortion of the magnetic field gradients, caused by eddy currents, by reflecting the actual shape of the applied test gradient waveform. |

1. A magnetic resonance imaging (MRI) apparatus comprising:
a magnetic assembly including:
a main magnet which includes a bore and forms a static magnetic field in the bore, anda gradient coil unit which is disposed around the bore and forms magnetic field gradients; and a gradient controller configured to apply a test gradient waveform to the magnetic assembly, and compensate for a distortion of the magnetic field gradients, caused by eddy currents, by accounting for an actual shape of the applied test gradient waveform. |
