Abstract:
A method includes obtaining a plurality of magnetic resonance (MR) coil images of a subject of interest, each MR coil image being generated from one of an array of MR receiving coils; combining the plurality of coil images to generate an image estimate of the subject of interest; performing a multichannel blind deconvolution (MBD) process including: deriving coil sensitivity information for every one of the array of MR receiving coils based on the image estimate or a filtered image estimate derived from the image estimate; updating the image estimate or the filtered image estimate using the derived coil sensitivity information to generate an updated image estimate; and applying a homomorphic filter to the image estimate to derive the filtered image estimate, or to the updated image estimate to derive a filtered updated image estimate, or a combination thereof.
