Spatial resolution of a small animal PET scanner needed to produce an image with the same sampling density as a human PET scanner with 3 mm spatial resolution imaging an adult human subject. Red line at 1 mm locates a typical resolution value for contemporary small animal scanners, 0.7 mm, a line that locates an estimate of the best possible physical spatial resolution, and a line at 0.2 mm that locates the resolution needed to image a mouse with human sampling density. Adult animal weights vary widely by age, sex and subtype for each specie and are included here only as a guide. rhe: rhesus macaque monkey; cyn: cynomolgus monkey.
