Spatio-temporal reconstruction of dPET data using complex wavelet regularisation.
Traditionally, dynamic PET studies reconstruct temporally contiguous PET images using algorithms which ignore the inherent consistency between frames. We present a method which imposes a regularisation constraint based on wavelet denoising. This is achieved efficiently using the Dual Tree Complex Wa...
