Analytical reconstruction of 4D dynamic cardiac SPECT with noise-reduction and non-uniform attenuation compensation
BACKGROUND: This study focuses on quantitative reconstruction of dynamic cardiac SPECT. MATERIAL AND METHODS: The Karhunen-Loeve (KL) transform is first applied to gated frames or sinogram data to de-correlate the dynamic information along the time direction. Then the Poisson noise is treated by a p...
