Abstract: A method for correcting image inhomogeneity includes acquiring a non-normalized image and a reference image using receiver coils. A high-signal mask and a low-signal mask are created. Each pixel in the high-signal mask is set to a predetermined integer value if the reference image pixel at the same specific location has a value above a threshold value. Each pixel in the low-signal mask is set to the predetermined integer value if the reference image pixel at the same specific location has a value below or equal to the threshold value. A coil normalization map is created by smoothing the reference image with filters. Then, an iterative procedure is performed to update the coil normalization map using the high-signal mask and the low-signal mask. Following the iterative procedure, the non-normalized image is divided by the current coil normalization map to yield a normalized image.

The partial datasets can be of an anatomical region of a patient delimited perpendicularly to a longitudinal direction within an acquisition region.

For at least one slice group including adjacent slices, the geometry information is compared to detect one or more discontinuities. For at least one discontinuity of the one or more discontinuities satisfying a correction criterion, the combined dataset is corrected as a function of the geometry information to eliminate or reduce the at least one discontinuity.
