Fig. 10.
2D slice of the KEM and MLEM reconstruction of the 3D FDG data resampled at varying count levels. All images have undergone post reconstruction smoothing, with the FWHM stated above each image. The width of the FWHM was chosen to minimise the NRMSE between the reduced dose image and the full count MLEM data, with 4mm post reconstruction smoothing. Reconstruction shown at 100 iterations.
