PROPELLER磁共振成像
摘要：
本发明提供了一种被配置用于根据PROPELLER磁共振成像协议从成像区(108)采集磁共振数据(142)的磁共振成像系统(100)。脉冲序列数据被配置为使得针对磁共振数据的多个刀锋中的每个的所述脉冲序列数据包括针对多个天线元件中的每个(126、126′、126″、126″′)同时采集的线圈特异性磁共振数据(146、146′、146″、146″′)。所述磁共振成像系统还被配置为针对每个刀锋执行以下操作：依据平行成像磁共振成像协议，根据针对每个天线元件的所述线圈特异性磁共振数据重建(214)刀锋图像(150、150′)；使用一组线圈灵敏度、所述刀锋图像以及所述线圈特异性磁共振数据来针对所述刀锋图像构建(218)Chi地图(154、154′)。
摘要（英）：

The invention provides for a magnetic resonance imaging system (100) configured for acquiring magnetic resonance data (142) from an imaging zone (108) according to a PROPELLER magnetic resonance imaging protocol. The pulse sequence is configured such that the pulse sequence data for each of the multiple blades of magnetic resonance data comprises coil specific magnetic resonance data (145, 146′, 146″, 146″′) acquired for each of multiple antenna elements simultaneously (125, 126′, 126″, 126″′). The magnetic resonance imaging system is further configured to perform the following for each blade: reconstruct (214) a blade image (150, 150′) from the coil specific magnetic resonance data for each antenna element according to a parallel imaging magnetic resonance imaging protocol, construct (218) a Chi map (153, 154′) for the blade image using the set of coil sensitivities, the blade image, and the coil specific magnetic resonance data.
