Method and System for Segmentation of the Liver in Magnetic Resonance Images Using Multi-Channel Features |
| 摘要 |
A method and system for fully automatic liver segmentation in a multi-channel magnetic resonance (MR) image is disclosed. An initial liver boundary in the multi-channel MR image, such as an MR Dixon scan. The segmented initial liver boundary in the multi-channel MR image is refined based on features extracted from multiple channels of the multi-channel MR image using a trained boundary detector. The features may be extracted from an opposed channel and a water channel of an MR Dixon scan. |

1. A method for liver segmentation in a multi-channel magnetic resonance (MR) image, comprising:
segmenting an initial liver boundary in the multi-channel MR image; and refining the segmented initial liver boundary in the multi-channel MR image based on features extracted from multiple channels of the multi-channel MR image using a trained boundary detector. |
