Percentage standard deviation \(\left( {\% {\text{STD}}_{{{\text{RC}}}} } \right)\) with different rod sizes and radionuclides with the a RAYCAN, b Inveon and c Molecubes systems. Most variability in the \(\% {\text{STD}}_{{{\text{RC}}}}\) is seen with 68Ga with rod size of 1 mm on the Molecubes system and with rod size of 1 mm and 2 mm on the Inveon system, reflecting system resolution. The RAYCAN system has more variability between radionuclides, where 68Ga shows the highest variability on nearly all rod sizes
