SNR and k-space filtering are the two key aspects characterizing the image quality. With k-space filtering quantification several acquisitions using different strategies (acceleration, sampling strategies) can be properly compared. First the quantification of k-space filtering of the standard hyperpolarized 3-Helium imaging methods has been performed. Secondly expected SNR of images acquired with different strategies but providing similar k-space filtering were simulated and analysed.
