Magnetic resonance imaging (MRI) probes signals through Fourier measurements. Accelerating the acquisition process is of major interest for various MRI applications. The recent theory of compressed sensing shows that sparse or compressible signals may be reconstructed from a small number of random measurements in a sensing basis incoherent with the sparsity basis. In this context, we advocate the use of a chirp modulation of MRI signals prior to probing an incomplete Fourier coverage, in thedoi:10.1109/isbi.2010.5490066 dblp:conf/isbi/WiauxPGTVV10 fatcat:vw4byopxyngyhngzn4jfycfrhq
