A programmable graphic radiation generator includes a processing unit and a radiation module, wherein the processing unit is used for receiving and processing a graphic signal so as to generate and output a group of graphic control signals according to the graphic signal. The processing unit includes an input end for receiving the graphic signal and a plurality of output ends for sending the graphic control signals. The radiation module herein is used for applying radiation energy to an object and includes a plurality of radiation units, each of the radiation units comprising an input end that is coupled to one of the output ends on the processing unit for receiving one of the graphic control signals. A radiation component is coupled to an external power source for generate corresponding radiation energy on the basis of the graphic control signal that is received by the output end of the processing unit. An output terminal is used for outputting the radiation energy.
