Improved low-count quantitative PET reconstruction with an iterative neural network

1 code implementation5 Jun 2019 Hongki Lim, Il Yong Chun, Yuni K. Dewaraja, Jeffrey A. Fessler

Image reconstruction in low-count PET is particularly challenging because gammas from natural radioactivity in Lu-based crystals cause high random fractions that lower the measurement signal-to-noise-ratio (SNR).
