2D slice of the MLEM and KEM reconstructions for reduced dose data of the 3D phantom. Reconstructions shown from 1% to 100% of the full count data, at 100 iterations. Kernel parameters used are stated in Table 1. k value varied with count level (10, 25, 25, 50, 50, 50 respectively). Tumour present in the PET data is not present in the T1 image. The location of the tumour is indicated by the red arrow.
