Image reconstruction using the wavelet transform for positron emission tomography.

Image reconstruction using the wavelet transform for positron emission tomography.

The authors conducted positron emission tomography (PET) image reconstruction experiments using the wavelet transform. The Wavelet-Vaguelette decomposition was used as a framework from which expressions for the necessary wavelet coefficients might be derived, and then the wavelet shrinkage was appli...
