| 中文摘要: |
| 随着高场MR设备的普及,由于传统梯度场的发展受到人体外周神经刺激(PNS)阈值的限制,使对快速成像技术的需求十分迫切,非线性梯度场并行成像技术由此得到越来越多的关注。本文介绍梯度场构建、并行接收、采样轨迹以及图像重建算法等技术,对非线性梯度场下并行成像技术的研究现状进行综述。 |
| 英文摘要: |
| With the popularity of high-field magnetic resonance devices, traditional gradient-field imaging has been limited because of the human peripheral nerve stimulation (PNS) threshold, so that fast imaging technology is urgently needed. The non-linear gradient field parallel imaging technique has attracted much more attentions. Recent progress of non-linear gradient field parallel imaging technology, including the gradient field construction, parallel receive technology, sampling trajectory and image reconstruction algorithms were reviewed in this article. |
