Axial slices of the MHS phantom positioned in the centre of the FOV for 18F with contrast 1/8 (top), F18 with contrast 1/4 (middle row) and 68Ga with contrast 1/8 (bottom row). Three different reconstruction settings are presented: 3D-OSEM (left column), PSF (middle column) and PSF with a 2-mm FWHM Gaussian filter (right column). The image window was normalized on the background of the phantom
