Central slices of the NEMA IEC image quality body phantom acquired during the image quality tests for the Discovery MI and Discovery MI-DR PET/CT systems. Images were reconstructed with the VPHD (3D OSEM), VPFX (3D OSEM + TOF), VPHD-S (3D OSEM + PSF), VPFX-S (3D OSEM + TOF + PSF) reconstruction algorithms and with Q.Clear, with β = 50 and β = 350. The gray-scale next to each phantom image represents the activity concentration in kBq/mL
