We have proposed a new image reconstruction technique in which images of an optional scale can be obtained and hence alias-free images can be reproduced from a single piece of data by applying a quadratic phase modulation to a Fourier imaging technique. Almost all the aliasing artifacts are removed, however, small aliasing artifacts that comes from the higher frequency components contained in the signal but not contribute to the down-scaled image are remained. In this paper, we propose a new alias-free reconstruction technique in which remaining aliasing artifact are reduced using SENSE-like algorithm.
