摘要: The invention relates to a method for obtaining PET crystal energy peak value and setting an frequency discriminator. the comprises steps of establishing distribution model acquiring original data, performing spectrum statistics based on data so as obtain initial fitting parameters crystal, adopting LM iterative algorithm calculate completing recognition according obtained crystal. By means technical scheme, optical can be obtained.
