MAGNETIC RESONANCE IMAGING APPARATUS AND METHOD FOR CALCULATING SPECIFIC ABSORPTION RATIO IN MAGNETIC RESONANCE IMAGING APPARATUS |
| 摘要 |
A magnetic resonance imaging apparatus includes a shifted RF power calculation unit, a specific absorption ratio calculation unit and a display control unit. The shifted RF power calculation unit shifts RF power, when a weight of an object or an imaging region of the object is smaller than or equal to or smaller than a threshold, in accordance with a difference between the weight and the threshold to calculate shifted RF power. The specific absorption ratio calculation unit calculates, when the weight is smaller than or equal to or smaller than the threshold, a specific absorption ratio based on the threshold and the shifted RF power. The display control unit displays the specific absorption ratio on a display device. |
