Among the various approaches for producing point distributions with blue noise spectrum, we argue an optimization framework using Gaussian kernels. We show that a wise selection of parameters, this approach attains unprecedented quality, provably surpassing current state art attained by optimal transport (BNOT) approach. Further, our algorithm scales smoothly and feasibly to high dimensions whi...

Objective(s): We evaluated edge artifacts in relation to phantom diameter and reconstruction parameters in point spread function (PSF)-based positron emission tomography (PET) image reconstruction.Methods: PET data were acquired from an original cone-shaped phantom filled with 18F solution (21.9 kBq/mL) for 10 min using a Biograph mCT scanner. The images were reconstructed using the baseline or...
