Abstract: | Scatter correction in single photon emission computed tomography(SPECT) has been focused on either using multiple-window acquisition technique or the scatter modeling technique in iterative image reconstruction.We propose a technique that uses only the emission data for scatter correction in SPECT.We assume that the scatter data can be approximated by convolving the primary data with a scatter kernel followed by the normalization using the scatter-to-primary ratio(SPR).Since the emission data is the superpo... |
