Illusion of proposed U2-Net architecture. It consists of 4 residual U-block (RSU) encoders with height of L, 3 bottom residual block (RS) and 4 symmetric RSU decoder. Skip connections are used to save spatial information along matched encoders and decoders. 1/7 SPECT and corresponding CT image are used as the input. The output of the network is images convoluted and upsampled from the second and third RS and follow-up decoders
