[en] To make all PMT's gains identical through auto-adjustment is important for ensuring the PET imaging quality. The response output depends on the light collecting efficiency in the position where the event happens and the energy of light quantum. Light collecting efficiency of PMT in the position is in proportion to solid angle of the PMT at the position. The adjusting value was calculated by the algorithm described in the paper. The result showed that the algorithm was effective in practice. (authors)
