Fig. 4From: Ultra high speed SPECT bone imaging enabled by a deep learning enhancement method: a proof of conceptZoomed visual results of different methods on synthesizing standard SPECT from 1/7 SPECT. The results are zoomed images from the same case using 1/7 scan time constructed with the OSCG algorithm, enhanced by EDSR network, RCAN network, ESRGAN network, proposed U2-Net, respectively, and the standard SPECT imageBack to article page
