title = "The investigation of emission reconstruction with fewer projection views for brain SPECT imaging",
abstract = "To reduce scanning time in SPECT brain imaging, we investigate new brain imaging procedures, that include both scanning protocols and image processing methods, while at the same time, retain the comparable image quality for brain SPECT study. We apply our previously proposed fast convergent reconstruction along with some post-processing methods for the few view data. In the preliminary results from our simulations and physical phantom studies, the mean reconstructed ROI to background (R/B) ratio remains relatively stable with few variation. This result illustrates that a substantial saving of acquisition time can be achieved by reducing the number of projection views in the brain SPECT studies. The result is achieved without a significant loss in quantitative accuracy by using an improved reconstruction method in combination with additional data processing procedures.",
