MRI APPARATUS |
| 摘要 |
An MRI apparatus comprising, a generating unit configured to generate radio frequency pulses applied in a pulse sequence; a sequence control unit configured to apply a radio frequency pulse related to acquisition of an image signal and a corrective radio frequency pulse during execution of one TR of a pulse sequence; and a calculation unit configured to measure the corrective radio frequency pulse and calculates a correction value of the radio frequency pulse, wherein based on the correction value, the generating unit corrects a radio frequency pulse related to acquisition of an image signal to be applied during a following TR later than a TR during which the corrective radio frequency pulse is measured. |

1. An MRI apparatus comprising:
a generating unit configured to generate radio frequency pulses applied in a pulse sequence; a sequence control unit configured to apply a radio frequency pulse related to acquisition of an image signal and a corrective radio frequency pulse during execution of one TR of a pulse sequence; and a calculation unit configured to measure the corrective radio frequency pulse and calculates a correction value of the radio frequency pulse, wherein based on the correction value, the generating unit corrects a radio frequency pulse related to acquisition of an image signal to be applied during a TR in a stage later than a TR during which the corrective radio frequency pulse is measured. |
