MAGNETIC RESONANCE IMAGING DEVICE AND CONTROL METHOD THEREOF |
| 摘要 |
An MRI apparatus performs an MRI while moving a patient table and includes a main magnet configured to generate a static magnetic field in a bore; a gradient coil assembly configured to apply a gradient signal to the static magnetic field to generate a magnetic field gradient; an RF coil assembly configured to apply an RF excitation signal and an RF refocusing signal; and a controller configured to control the RF refocusing signal so that a slice to which the RF refocusing signal is to be applied conforms to the slice to which the RF excitation signal has been applied. |

1. A magnetic resonance imaging (MRI) apparatus to perform MRI while moving a patient table, the MRI apparatus comprising:
a main magnet configured to generate a static magnetic field in a bore; a gradient coil assembly configured to apply a gradient signal to the static magnetic field to generate a magnetic field gradient; a radio frequency (RF) coil assembly configured to apply an RF excitation signal and an RF refocusing signal; and a controller configured to control the RF coil assembly so that a slice to which the RF refocusing signal is to be applied conforms to the slice to which the RF excitation signal has been applied. |
