The invention provides for a magnetic resonance imaging system (100, 300, 500) comprising a radio-frequency system (114, 116) comprising multiple coil elements (114) for acquiring imaging magnetic resonance data (166) from a subject (118). The magnetic resonance imaging system further comprises a memory (150) for storing machine executable instructions (160). The memory further stores imaging pulse sequence commands (164). The imaging pulse sequence commands are configured for controlling the magnetic resonance imaging system to acquire the imaging magnetic resonance data according to a chosen parallel magnetic resonance imaging protocol. The magnetic resonance imaging system further comprises a processor (144) for controlling the magnetic resonance imaging system. Execution of the machine executable instructions causes the processor to: control (200) the magnetic resonance imaging system to acquire the imaging magnetic resonance data using the pulse sequence commands； and reconstruct (202) an imaging magnetic resonance image (168) from the imaging magnetic resonance data according to the chosen parallel magnetic resonance imaging protocol. The imaging magnetic resonance image is reconstructed by maximizing consistency between the imaging magnetic resonance data, the imaging magnetic resonance image, and an imaging coil sensitivity map (162). After reconstructing the imaging magnetic resonance image, the processor stores (202) the imaging coil sensitivity map in the memory.
