Improved low-count quantitative PET reconstruction with an iterative neural network
Hongki Lim, Il Yong Chun, Yuni K. Dewaraja +1
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 measurem…
