Image reconstruction system and method in magnetic resonance imaging

A system comprising an MRI device and a computing device, the MRI device including multiple radio frequency (RF) receiver coils, the computing device including a processor, wherein during operation, the processor causes the system to:

• receive, by the multiple RF receiver coils, MR signals of an object;
• generate, by the processor, multiple coil images of the object based on the MR signals, the multiple coil images including a first set of coil images and a second set of coil images;
• generate, by the processor, a first reconstructed image based on the first set of coil images according to a first reconstruction algorithm and generate a second reconstructed image based on the second set of coil images according to a second reconstruction algorithm, the second reconstruction algorithm being different with the first reconstruction algorithm;
• generate, by the processor, correction information about the first reconstructed image by dividing the first reconstructed image by the second reconstructed image;
• and
• generate, by the processor, a corrected image with reduced inhomogeneity intensity based on the first reconstructed image and the correction information about the first reconstructed image.

A non-transitory computer readable medium comprising executable instructions that, when executed by at least one processor, cause the at least one processor to effectuate a method comprising:

• receiving MR signals of an object, the MR signals being acquired by multiple RF receiver coils of an MR device;
• generating, by the at least one processor, multiple coil images of the object based on the MR signals, the multiple coil images including a first set of coil images and a second set of coil images;
• reconstructing, by the at least one processor, a first reconstructed image based on the first set of coil images based on a first reconstruction algorithm;
• reconstructing, by the at least one processor, a second reconstructed image based on the second set of coil images based on a second reconstruction algorithm, the second reconstruction algorithm being different with the first reconstruction algorithm;
• generating, by the at least one processor, correction information about the first reconstructed image by dividing the first reconstructed image by the second reconstructed image;
• and
• generating, by the at least one processor, a corrected image with reduced inhomogeneity intensity based on the first reconstructed image and the correction information about the first reconstructed image.
