System and method of receive sensitivity correction in mr imaging

A method of magnetic resonance imaging (MRI) comprising:

• generating a proton density weighted image of an object;
• determining a transmit sensitivity map from a B1+ field map of the object;
• generating a transmit-corrected image of the object based on the transmit sensitivity map and based on the proton density weighted image;
• low-pass filtering the transmit-corrected image to generate a receive sensitivity map;
• and
• correcting an MR image using the receive sensitivity map.

A computer readable storage medium having stored thereon a computer program comprising instructions, which, when executed by a computer, cause the computer to:

• generate an original image of an object;
• obtain an MR image of an object;
• obtain a proton density weighted image of the object;
• obtain a B1+ field map of the object;
• generate a transmit-corrected image based on the B1+ field map and based on the proton density weighted image;
• electronically filter the transmit-corrected image to generate a receive sensitivity map;
• and
• refine the original image using the receive sensitivity map.
