Thesis: Level-Weighed Wavelet Fusuion: A Soft Decision Image Fusion Technique - Multi-coil MR images are conventionally combined using a magnitude sum. A problem with this approach is the loss of contrast due to the global lowpass filtering operation. Wavelet methods have been shown to be useful for reducing receiver sensitivity inhomogeneity in multi-coil applications, but not much work has been done to alleviate the loss of resolution. We present a novel Level-Weighted Wavelet Fusion (LWWF) scheme to address this. We show that the method is successful improving the contrast in multi-coil brain images at 3 Tesla.
