MAGNETIC RESONANCE IMAGING WITH DIFFERENT FREQUENCY ENCODING PATTERNS |
| 摘要 |
In a method and control device for magnetic resonance imaging, raw magnetic resonance data are acquired from one region of an examination object by a number of magnetic resonance receiving antennas of a magnetic resonance system. Calibration values are determined that represent the sensitivity of at least one of the magnetic resonance receiving antennas. An image reconstruction is performed on the basis of the raw magnetic resonance data, taking into consideration the determined calibration values. The determination of the calibration values is frequency-dependent. |

1. A method for magnetic resonance imaging, comprising:
operating a magnetic resonance scanner to acquire raw magnetic resonance data from a region of an examination subject via a number of magnetic resonance receiving antennas of the magnetic resonance scanner, each of said magnetic resonance receiving antennas having a sensitivity; in a processor, making a frequency-dependent determination of calibration values that represent the sensitivity of at least one of said magnetic resonance receiving antennas; and in said processor, executing an image reconstruction algorithm to reconstruct an image based on the raw magnetic resonance data, dependent on the determined calibration values. |
