AUTOMATIC ARTIFACT DETECTION AND PULSE SEQUENCE MODIFICATION IN MAGNETIC RESONANCE IMAGING

摘要

The invention provides for a magnetic resonance imaging system (100, 300). The execution of machine executable instructions causes a processor (130) controlling the magnetic resonance imaging system to control (200) the magnetic resonance imaging system to acquire the magnetic resonance imaging data (144) using pulse sequence commands (142) and reconstruct (202) a magnetic resonance image (148). Execution of the machine executable instructions causes the processor to receive (204) a list of suggested pulse sequence command changes (152) by inputting the magnetic resonance image and image metadata (150) into an MRI artifact detection module (146, 146′, 146″). The MRI artifact detection module comprises at least one neural network, which has been trained using images from failed magnetic resonance imaging protocols and/or magnetic resonance data extracted from the magnetic resonance imaging protocols labeled as failed accessed from a log file (312) which logs the execution of previous magnetic resonance imaging protocols. Execution of the machine executable instructions further causes the processor to receive (206) a selection of a chosen pulse sequence command change (158) from the list of suggested pulse sequence command changes. Execution of the machine executable instructions further causes the processor to modify (208) the pulse sequence commands using the chosen pulse sequence command change.
