Fig. 7.
Coefficient of variation vs mean value for a white matter region and the right caudate, calculated for the KEM and MLEM reconstructions of the simulated data. The corresponding value for the MLEM reconstruction of the no noise data at 300 iterations is shown by the single black square, with the KEM reconstruction of the no noise data shown by the black star. The ground truth value for the caudate region and the white matter region are 0.306 and 0.116 respectively.
