Abstract:
The invention provides for a magnetic resonance imaging system (100, 300) comprising: a radio-frequency system (116, 122, 124, 126, 126′, 126″, 126′″) for acquiring magnetic resonance data (152) from an imaging zone (108), wherein the radio-frequency system comprises multiple antenna elements (126, 126′, 126″, 126′″); a memory (140) containing machine executable instructions (170) and pulse sequence commands (150), wherein the pulse sequence commands cause the processor to acquire magnetic resonance data from the multiple antenna elements according to a SENSE protocol; and a processor. Execution of the machine executable instructions causes the processor to: control (200) the magnetic resonance imaging system with the pulse sequence commands to acquire the magnetic resonance data; reconstruct (202) a preliminary image (154) using the magnetic resonance imaging data; calculate (204) a fit (159) between an anatomical model (156) and the preliminary image, wherein the anatomical model comprises a motion likelihood map (158); identify (206) at least one image artifact origin (160) at least partially using the motion likelihood map and the fit; determine (208) an extended SENSE equation (162) at least partially using at least one image artifact origin; and construct (210) a corrected SENSE image (164) using the extended SENSE equation.
