Fig. 7From: Deep learning approximation of attenuation maps for myocardial perfusion SPECT with an IQ\(\varvec{\cdot {}}\)SPECT collimatorPixel-wise correlation maps between DLAC and CTAC polar maps on the left and nAC and CTAC polar maps on the right for all test split images. The correlation was calculated using pixels in the circular region of the polar maps at a resolution of \(512\times {}512\)Back to article page
