Iterative PET Image Reconstruction Using CNN Representation

result

Prerequisites

Matlab, Python 2.7, Tensorflow 1.4

Instructions

Note

  • The 3D U-net is trained and the trained model is stored in pretraining_process. If you want to re-train the model based on your own data sets, you can use Unet3D_train.py for training and Unet3D_test.py for testing.
  • The results runing on Ubuntu server setting penalty parameter rho = 7.5e-4 are uploaded for reference.
  • If you do not have training data, but have the anatomical prior image, you can check my newly published DIPRecon method.
