TL;DR: Full 3D U-net is superior to several existing denoising methods, including Gaussian filter, anatomical-guided non-local mean (NLM) filter, and MAP reconstruction with Quadratic prior and relative difference prior, in terms of superior image quality and trade-off between noise and bias.

TL;DR: The results showed that LSO background adds concentric ring artifacts to the reconstructed image, and the simple subtraction method can effectively remove these artifacts-the effect of the correction was more visible when the object activity level was near or above the eMDTA.

TL;DR: Respiratory motion can have a substantial impact on dynamic PET in the thorax and abdomen and the INTEX method using continuous external motion data substantially changed parameters in kinetic modeling.

TL;DR: A new method has been developed that requires only a uniform flood source to irradiate a crystal array without the need to locate the interaction positions, and calculates DOI functions based solely on the uniform probability distribution of interactions over DOI positions without knowledge or assumption of detector responses.

TL;DR: A scatter and crosstalk correction method for (99m)Tc/(123)I dual-radionuclide imaging for a CZT-based dedicated cardiac SPECT system with pinhole collimators and is validated using Monte Carlo simulation, line source experiment, anthropomorphic torso phantom studies, and patient studies.
