Method, system, and computer program product utilizing spatially-resolved b1 amplitude-based tuning of magnetic resonance images

A Magnetic Resonance Imaging (MRI) system comprising:

• a gantry;
• at least one RF transmitter coil;
• and
• an RF transmitter coil controller configured to:
• obtain spatially-resolved B1 amplitude measurements obtained using at least one RF parameter;
• perform at least one spatially-resolved analysis on a spatially-resolved subset of the obtained spatially-resolved B1 amplitude measurements;
• determine an updated value of the at least one RF parameter to be used in a series of MRI sequences based on the performed spatially-resolved analysis;
• and
• store the updated value of the at least one RF parameter.

A computer program product comprising:

• a computer readable storage medium configured to be communicatively coupled to a computer processor, wherein the computer readable storage medium includes computer instructions which, when executed by the computer processor, cause the computer processor to perform the steps of:
• obtaining spatially-resolved B1 amplitude measurements obtained using at least one RF parameter;
• performing at least one spatially-resolved analysis on a spatially-resolved subset of the obtained spatially-resolved B1 amplitude measurements;
• determining an updated value of the at least one RF parameter to be used in a series of MRI sequences based on the performed spatially-resolved analysis;
• and
• storing the updated value of the at least one RF parameter.
