“…Conventional Fourier imaging meets the relaxed CS conditions: most MR images are compressible with identity transform or wavelet transform and the Fourier encoding is sufficiently incoherent with these sparsifying transforms (19). The SparseMRI method fully samples the k-space along the readout direction and randomly undersamples the k-space along the phase-encoding direction, using a variable-density sampling scheme with denser sampling near the center of the kspace.…”

“…concept a Ă©tĂ© introduit sous le nom d'acquisition comprimĂ©e (compressed sensing) (Donoho 2006 ;Lustig et al 2008). Son principe est de tirer parti de redondances spatiales ou temporelles prĂ©sentes dans certaines reprĂ©sentations de l'objet sousjacent, ainsi que de l'incohĂ©rence des artefacts gĂ©nĂ©rĂ©s par un Ă©chantillonnage irrĂ©gulier, pour Ă©viter de remplir des pans entiers de la matrice d'acquisition tout en reconstruisant une image avec un minimum de perte de qualitĂ©.…”

“…Compressive sensing has been particularly successful in multidimensional imaging applications, including magnetic resonance [5], projection [6], [7] and diffraction tomography [8], spectral imaging [9], [10] and video [11], [12]. Conventional sensing systems typically first acquire data in an uncompressed form (e.g., individual pixels in an image) and then perform compression subsequently, for storage or communication.…”
