Hypothesis
Can a new postprocessing method effectively compensate for scatter and blurring in SPECT images?
Conclusion
The proposed method significantly improves image quality and quantitative accuracy in SPECT imaging.
Supporting Evidence
- Image contrast improved by 25% compared to uncompensated images.
- Error decreased by 40% compared to uncompensated images.
- The method is faster than traditional iterative methods, taking only a few minutes.
Takeaway
This study shows a new way to make SPECT images clearer and more accurate by fixing problems caused by scattering and blurring.
Methodology
The study used Monte Carlo simulations and a two-dimensional point spread function to model and compensate for scatter and blurring in SPECT images.
Limitations
The method is developed in two dimensions and does not account for scattered photons from out-of-plane sources.
