    • The invention provides for a magnetic resonance imaging system (100) for acquiring magnetic resonance data (142, 144) from an imaging zone (108). Execution of the instructions causes a processor (133) controlling the MRI system to: acquire (200) imaging magnetic resonance data (142) with radio frequency excitation of the radio frequency system enabled; acquire (202) noise radio frequency data (148) using at least one RF noise detection coil, wherein the noise radio frequency data is acquired simultaneously with the imaging magnetic resonance data; acquire (204) calibration magnetic resonance data (144) with radio frequency excitation of the radio frequency system disabled; acquire (206) reference radio frequency data (146) using the at least one RF noise detection coil, wherein the reference radio frequency data is acquired simultaneously with the calibration magnetic resonance data; and calculate (208) a noise calibration (150) using the reference radio frequency data and the calibration magnetic resonance data.
    • 本发明提供一种用于从成像区域(108)获取磁共振数据(142,144)的磁共振成像系统(100)。 所述指令的执行使得控制所述MRI系统的处理器(133)利用所述无线电频率系统的射频激励获取(200)成像磁共振数据(200); 使用至少一个RF噪声检测线圈获取(202)噪声射频数据(148),其中与成像磁共振数据同时获取噪声射频数据; 利用无线电频率系统的射频激励来取得(204)校准磁共振数据(144); 使用所述至少一个RF噪声检测线圈获取(206)参考射频数据(146),其中所述参考射频数据与所述校准磁共振数据同时获取; 并使用参考射频数据和校准磁共振数据计算(208)噪声校准(150)。
