By applying 3D compressed sensing (CS) method to
accelerate the acquisition time of chemical-shift
imaging (CSI) which doesnt possess the sparseness
required by conventional 2D slice type CS. When the
entire CSI data set is treated as one unity, CS can be
satisfactorily applied to spectroscopic CSI to reduce
acquisition time which is very desirable for possible
multiple CSI acquisition during the lifetime of
hyperpolarized agent for metabolic dynamic analysis such
as Hyperpolarized 13C metabolism research.
