MAGNETIC RESONANCE IMAGING APPARATUS AND MAGNETIC RESONANCE IMAGING METHOD |
| 摘要 |
A magnetic resonance imaging apparatus according to an embodiment includes a temperature sensor and a processing circuit. The temperature sensor acquires a temperature. The processing circuit calculates, based on information on an imaging sequence in which magnetic resonance imaging is to be performed, an estimated value of consumption energy of a gradient coil in a case when the imaging sequence is executed and calculates, based on the temperature acquired by the temperature sensor and the estimated value of the consumption energy, an estimated value of a temperature of the gradient coil, the temperature of the gradient coil undergoing changes as the imaging sequence is executed. |
