MODIFICATION OF PULSE SEQUENCE PARAMETERS FOR MAGNETIC RESONANT VISUALIZATION

摘要

The invention provides for a magnetic resonance imaging system (100) for acquiring magnetic resonance data (154) from an imaging zone (108). The magnetic resonance imaging system comprises: a memory (136) for storing initial pulse sequence commands (140) and machine executable instructions (160); and a processor (130) for controlling the magnetic resonance imaging system. Execution of the machine executable instructions causes the processor to receive (200) a set of selected pulse sequence parameters (142) comprising a definition of a region of interest (109) of a subject (118). The region of interest is within the imaging zone. Execution of the machine executable instructions further causes the processor to send (202) an image data request to a historical database (138). The image data request comprises the set of selected pulse sequence parameters. Execution of the machine executable instructions further causes the processor to receive (204) historical image data (146, 306, 308, 310, 312, 314, 402) from the historical database in response to the image data request. The historical database comprises multiple image data entries. Each image data entry comprises a set of historical pulse sequence parameters (502). The historical database is configured to search the historical database to retrieve the historical image data by matching the set of selected pulse sequence parameters to the set of historical pulse sequence parameters. Execution of the machine executable instructions further causes the processor to display (206) at least a portion (148) of the historical image data on a user interface. Execution of the machine executable instructions further causes the processor to receive (208) scan input modifications (150) in response to displaying the at least a portion of the historical image data on the user interface. Execution of the machine executable instructions further causes the processor to generate (210) modified pulse sequence commands (152) using the initial pulse sequence commands, the set of selected pulse sequence parameters, and the scan input modifications. Execution of the machine executable instructions further causes the processor to control (212) the magnetic resonance imaging system to acquire the magnetic resonance data using the modified pulse sequence commands.
