Training End-to-End Unrolled Iterative Neural Networks for SPECT Image Reconstruction
Zongyu Li, Yuni K. Dewaraja, Jeffrey A. Fessler
Training end-to-end unrolled iterative neural networks for SPECT image reconstruction requires a memory-efficient forward-backward projector for efficient backpropagation. This pap…

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…
