DYNAMIC PET RECONSTRUCTION ALGORITHMS USING EMPIRICAL MODE DECOMPOSITION REGULARISATION

Abstract:

Dynamic PET enables quantitative analysis of in-vivo metabolic activity. Commonly, each image in a temporal sequence is reconstructed independently using standard methods developed for static PET.We present reconstruction methods which use Empirical Mode Decomposition (EMD) based regularization. The methods extend conventional static OSEM reconstruction to ensure consistency between temporal frames. Various data-driven denoising methods are evaluated. The EMD denoising scheme has advantages o...
